Simplifying a rational radical expression by multiplying by the conjugate

8 years later and you're still indirectly aiding students. Thank you Mr. McLogan, you seem like a wonderful instructor

I always watch your videos when I need to study for my finals!

[@gatorbait9878]

One of my students suggested to mic the audience. I'm not sure that its the best idea, but it could be entertaining.

[@emjaydark2811]

Your videos deserve a prize.

[@lucianastevens]

Your practice problem was the exact problem I was having trouble with!! Thank you so much!!

[@rajbanares5011]

There are flaws on your teaching but still taught me the concept of conjugate (from the word that defines marriage so it means one has to be opposite sex of the other so if the denominator has negative sign the conjugate must be positive thus in this case it's - 1 and +1). Good tutorial video

[@mariagotherstrom9533]

Thank god for this video. It saved me so much trouble.

[@kila5147]

Thank you for this video! I'm watching it today because tomorrow is our exam

[@brianmclogan]

Good luck!!

Very helpful thank you

Thank you my good sir, you are my hero

[@yusufkaya1393]

the thing that didnt clicked to me for now how did you simplyfy the 2 when your terms seperated by addition and subtraction

[@AbdoTechChannel]

Thanks

[@brianmclogan]

you are very welcome!

[@mitchbrook4112]

in the final steps, why does √5 not also change when changing 2/4 to 1/2?

[@victorsoto2188]

It looks like the 4 in the denominator should have been 5, ( 2sq of 5 plus 1 over 5). It happens but I like his videos. Peace

[@lfblopez2630]

What about if I do have a cube root instead of a square root?

[@gabbimarie1835]

thank you

[@pitoumil7447]

why some of your video the square should be conjugate? but this the negative 1 turn to positive 1.

One little mistake. It is just -1 and not -1 ^2. He showed in the example: (x+1)(x-1) == x^2 -1. Not -1^2

[@krishnasairaval3691]

the answer will still be the same. he's right. he just expanded it for the students to understand. difference of two squares (a+b)(a-b) = a^2 - b^2

[@willthomas7950]

I don't understand the part to the most left everything else is good. - It would take a long time to understand conjugates and to develop a simplify eye.

[@valentinabenavides3723]

huh?

[@RushilJain-si2hx]

Isnt this completely wrong? This kids raised proper questions lol. How can sqrt(5)*sqrt(5) = sqrt(5) as you did in the video, contrary to what you said which was true, that it just leaves us with 5. Secondly, how can two 2s be reduced using just one 4 in the denominator? It can only cut down one 2, and the other 2 remains as a 2.

[@Raymonster_1]

bald lol

[@sunitadiwaker2432]

it’s wrong

[@brianmclogan]

let me know where the mistake is so I can pin your comment so others are not confused

[@andreweroh]

@@brianmclogan isn't -1 squared actually going to be positive one?

[@denisepagaduan]

@@andreweroh in this case, we are not squaring -1, we are only squaring 1.

[@granth.4299]

-1² = -1. (-1)² = 1. The parentheses determine whether or not the negative operator is included when evaluating the exponential expression.

[@hchow6024]

i try to avoid your videos because when you talk all i hear is blah blah blah

[@brianmclogan]

sorry none of my videos have helped you but thankfully there are a lot of other great instructors out there that might be a better fit for you
