Synthetic Division and Remainder Theorem

[@patriciodoig7962]

THANKS Mr. H. ,I am an old student of 66 years and you give new methods for win time .

Who wants this man to be his high school teacher.

[@janoycresva276]

I had a really great math teacher during my junior year of high school, he taught me this & I loved math then.

[@jxyvsn5630]

✋

[@Odijis]

Screw that, I want him in grad school

[@AllenGoodwin-h8o]

I would gladly have him as my math teacher. His explanations are simple and clear. his writing on the other hand only gets a grade of C.

[@haroldharris9832]

I was never taught synthetic division. This was great. A good way to double check your work.

[@chocolateangel8743]

It only works when x is to the first power.

You sir are a gift to humanity.

[@ricardomeneses3393]

THANK YOU Mr. H. I used to be good at math. Now I am 65years old and one of my hobbies is to remember again and learn again.

[@srikantsingh6533]

I remember learning both long division and kind of synthetic Division methods as well as remainder theorem in my 9th standard.. but I never applied it this way.. it always worth giving time to your videos.. I revised as well as learnt such a surreal application. Wholeheartedly thank giving to you sir for uploading it on KZbin and connecting with us.. may God help you achieve your summit..😊

[@sreedhar75perupally]

Sir Good Morning 🙏 You are Unique in your Math Teaching.... Almighty Bless You Sir

[@lioncaptive]

First thing first - I zoom in to Mr H's videos and gain a wealth of knowledge. Math stablizes -- making me a fervent admire of your lessons.

[@markdonnelly1913]

You have a fantastic ability to make what initially looks like a difficult problem into an easily solvable one. I wish all mathematics teachers that I ever had would have broken it down so easily and quickly. Thank you.

[@mrhtutoring]

Thank you very much!

This is polynomial made easy.Much love from Nigeria

[@williamjoyner4251]

Some people will say you cannot do synthetic if the denominator is like 2x + 1 or 3x - 5, but you can. You will have a fraction on the outside and have to divide your final answer (except the remainder) by the denominator of the fraction.

[@WalterFernandes-du7om]

You're just superb dear Sir. You make these explanations so simple to understand. Way to go .. keep going string....

I learned synthetic division in university, but we call it Horner's Method. It's so convinient.

I am learning a lot that will be useful in my own teaching from this wonderful teacher

@@mrhtutoring thank u sir ❤️

[@piccolo64]

Beautiful and simple proof 🤩 Let P(x) be a polynomial of degree n To perform the division of P(x) by (x - a), we use the method of polynomial division. Let q(x) be the quotient (polynomial of degree n-1) and r be the remainder of this division: P(x) = q(x) * (x - a) + r Now, let's evaluate this equation at x = a: P(a) = q(a) * (a - a) + r Since (a - a) is equal to zero, we get: P(a) = r

[@chocolateangel8743]

The long polynomial division method is good for those that view division as repeated subtraction. However, for those of us that view division through the lens of multiplication, an area model might be easier to understand. I would encourage you to through up a video on that, when you have the time. Oh, it's also faster than long division, works all the time, and takes up less space. Since I have a preference for it, I don't care for synthetic division (or how it's typically taught).

What are or is the basic principal behind finding the root of the linear denominator, and the explanation to its relationship to the "x" in the numerator, please, respectively?

[@Zen-x2e]

First time i heard it and it gonna save lot of time 😆

[@AnouckJourdaa-kz8nk]

Great video, clear and straight to the point. I cringe at the chalk sound though, if you could use a whiteboard instead it would be better :)

[@mohammadishaq5299]

❤❤❤🎉🎉🎉 Excellent

[@vidlover7875]

If you have a quadratic in the denominator, could you factor out both of the linear factors, and then use both values of x (if multiple) as the dividend (for the synthetic division)?

[@fullc0de]

Nice!

[@JoeyHernandez-w5l]

A common mistake that one makes, when not in class, is because we miss out on the rules by not being in class when we are supposed to be . I see that now but it is never too late for miss lessons.

Can you solve for a function? So P(f(x)) such that f(x) is some function of x?

There are new methods now for Synthethic Division Non Linear, it is doable with Horner but it is modified

What if the p(5) was negative, like p(-5)

[@WalterFernandes-du7om]

Do you have a video on zerors of a polynomial

[@RobG1729]

I like your way of explaining. In the first division, you didn't have a close parenthesis for the expressions being subtracted.

[@sander_bouwhuis]

I love the long division! I'm not so sure about the synthetic division though. What if the denominator in the first example is something like 2x^2-10x+4=0? Long division still works then, but synthetic division will return 2 solutions for the denominator. In fact, what if the denominator only has complex solutions, like 2x^2-3x+4?

[@mrhtutoring]

Synthetic division only works when the divisor is power of 1

[@carultch]

Synthetic division still works when you have no real solutions. You would need to appeal to complex numbers to find your component polynomials. It's much easier to use polynomial long division, any time you don't have a real root to work with. Consider the example of: x^4 - 2 x^3 + 6 x^2 - 2 x + 5 which has no real solutions, but has a known factor of (x^2 + 1). This means two of its complex solutions are x = i and x = -i, Synthetic division with x = i as one root, pens out as follows: i |_1__-2______6_______-2_______5__ . .______i_____-1-2*i____2+5*i___-5__ . . . 1 . -2+i . . 5-2*i . . . . 5*i . . . 0 Continue the same process, using x = -i. -i |__1___-2+i____5-2*i____5*i___ . . _______-i______2*i______-5*i___ . . . . 1 . . -2 . . . . 5 . . . . . . 0 Resulting factored form: (x^2 - 2*x + 5)*(x^2 + 1)

[@adgf1x]

X^3+3x^2-4x-12=x^3-2x^2+5x^2-10x+6x-12=(x-2)(x^2+5x+6).thus quotient is:x^2+5x+6.ans

[@maryjudithachulang9016]

Hi! Can you use synthetic division when the divisor is a quadratic or even any degree more than two???

[@mrhtutoring]

Synthetic division is used only when the divisor is a degree of one.

It's quite helpful. Much quicker and efficient than the long division method.

[@marcusgloder8755]

My solution, without watching the video or reading other comments. 😎 (x³ + 3x² - 4x -12) : (x - 2) DIV 3 2 1 0 ‐--------------------------------------------- 2 1 3 -4 -12 2 10 12 ----------------------- 1 5 6 0 Solution x² + 5x + 6 A requirement is a divisor of the form (x + a) with a ∈ ℝ. Best regards Marcus 😎

[@shxniyx]

1:11 how in the heck is it positive. it’s always one thing after another with math that just confuses me. i thought i had it right saying it would be x^2 but nooooo somehow it’s a POSIVE 5x ..??? how when they have different signs??? i’m not saying you’re wrong i just don’t understand

[@-_IT_-]

Why is it a 5x³ and not an x³, If you are subtracting 3x³ from 2x³?

[@jamesharmon4994]

Because you are subtracting a negative 2 from a positive 3.

[@mrhtutoring]

Thank you for pointing it out. I missed that one.

[@trippies2000]

5:06 you mean x² not 1x²

[@carultch]

They both mean the same thing. x^2 implicitly means 1x^2.
