Another way to do it, without having to guess-and-check: first complete the square, x² - 2x - 48 = (x - 1)² - 49. This is a difference of squares, so it's easy to factor: ( (x - 1) + 7) ( (x - 1) - 7). So the end result is (x + 6) (x - 8). May take a bit longer at first, but if one is used to completing the square, it's quite fast.

While you do have some fun facts, the methods are too slow for practical application. Speed and experience is what should be taught after the basic understandings are demonstrated. It is lightening fast to just use the quadratic equation in your head. In the class test, you have to "Show your work." So yes we can play the games with the x and factor method for the teacher. But at work the quadratic is all you need to apply. In electronics, road work, engineering, etc., because the answers are usually complex, thise methods are seldom used.

There is another method on factoring with leading coefficient. Multiply the leading coefficient of x² to the constant. Do the usual factoring, then divide each constants with the leading coefficient of x². If one constant equals the whole number, retain the quotient as a factor. If the other constant is not divisible with the leading coefficient, copy that leading coefficient to x. Ex: 2x²+11x-6 Multiply 2 to -6, x²+11x-12 Factor out: (x-1)(x+12) Divide all constant by leading coefficient 2 from the original equation: (x-1/2)(x+12/2) Simplify: (x-1/2)(x+6)... Carry over the /2 from x-1/2 and transfer the 2 to x Answer: (2x-1)(x+6)
@helpwithmathing 2 ай бұрын
@barneyDcaller. This method is really intriguing, and seems to work as long as the leading coefficient is a prime number; I'm wonder how it works when the leading coefficient has multiple factors, such as 6x^2 - 7x - 5. You multiply the 6 times the -5 to get -30, factor to get (x-10)(x+3). Divide each constant by 6 and neither is an integer, nor is the answer (6x-10)(6x+3). How do you adjust this method to still work when the leading co-efficient itself has multiple factors?

What are asymptotes? And what do they do?
@helpwithmathing 2 ай бұрын
OK, @johnlakin5895. video soon, but briefly, asymptotes are lines that a function approaches but never hits. In graphic rational equations, we find the vertical and horizontal asymptotes of a function to help us graph it (look at my videos in the Pre-Calculus play list on graphing rational function). Similarly, if you think of the graph of the trig function Tangent, which is Sine/Cosine everywhere the Cosine function is zero will be an asymptote in the Tangent function since you cannot have a zero on the bottom of a function. That's the quick answer. More soon...

@johnlakin5895. Great questions and honestly, I'm not sure. In the US, math gets divided up by subject matter. An ordinary course of study would be Geometry in the first year of high school, Algebra II/Trig the second year, Pre-Calculus (a very rigorous course looking back at Algebra I and II, Geometry and Trig but taking each subject to its most complicated problems) and then Calculus I and II. Students on an advanced track will start with Algebra II Trig as their first high school year and end at Multivariable Calculus their final year. Students who need more time to achieve will start with Algebra I and end with Pre-Calculus. And Statistics is set aside as its very own course, which can be taken any time after Algebra II. How does that map onto O levels and A levels?

@@helpwithmathing O levels were typically taken at the end of secondary school (16 years) A levels were typically where the student concentrated on a few subjects, (usually three) and would be examined at the end (18 years old). I took three A levels (chemistry, geology and zoology) at this age. This was in the mid 70's ! A lot of students still went to the same school (called the sixth form for this age group). I went to a further education college for mine - my school was very small and could not begin to cater for post 16 education. It was expected that all students passed O levels in both English and maths (at least) included in a total of around five O levels to undertake A levels (maths especially, if you were going to study any science subjects. As I understood this video, I'm guessing at O level!

@vespa2860 This is instructive for me, thank you!, because I actual had a section explaining that (h,k) in a parabola is the horizontal and vertical shift of the (0,0) vertex of the parent equation, but I decided that people looking for information on focus and directrix were probably already familiar with vertex and would be bored. However, I think there is a need to link to a "pre-video" to this one that talks about translations, transformations and reflections specifically for quadratics. I do have this one, which might be a good start until I make a new one: kzbin.info/www/bejne/hJLOZJJ-eqp5i9U

Some posit that H stands for horizontal and K would be vertiKal, but that doesn't sound legit to me. Let me know if your research leads to anything, but otherwise they are just the letters assigned in American math to the horizontal/vertical shifts of vertex in parabolas and centers in Ellipses, Circles and Hyperbolas. (I've got videos on those if you look into the Pre-calculus playlist, but they are very early in my channel and probably could use a refresh now that I've gotten more seasoned at making channel content.

@@helpwithmathing Yes, I've seen a and b used here (England). I also figured that h could refer to horizontal, but k! Thought they might be referencing some Latin/Greek origin. but I gave up a few years ago when I was getting nowhere. I'll look at your video linked above again. So thanks for that.

Why not( -12x ) +2x? i.e-12x+2x

@angelsmileyprettyprincesss. Thanks so much for asking!! Not only to we need them to add to -10, but we also need them to multiply to positive 24. (-12) x (2) will be -24. So that pairing won't work, leaving us with (-4) x(-6) which both adds to (--10) and multiplies to positive 24. Does that clear that up? If not, ask more questions.

@@helpwithmathing Yes, it works. A small error (flipping the numerator/denominator) which doesn't really change the point you were making (change of form).
