Question

Divide the following polynomial, then place the answer in the proper location on the grid. Write your answer in order of descending powers of x.

(x^3 + y^3)/(x - y)

Answer 1

i don't want to just solve it for you
there are 2 ways to solve this.
Long division and synthetic division you may review your lesson or you may check khan academy they provide great explanations

Answer 2

i'll help you

Answer 3

I don't know how to do any of this because my teacher doesn't do anything but sit on his butt and get paid. I'm getting frustrated

Answer 4

okay i want you to watch this video and then we will solve this together.

Answer 5

i'll be right here for you just let me know when we start to solve

Answer 6

Ok so I think I get it a little, but I still need help

Answer 7

No problem but anyway here.. we won't use synthetic division why? because our divisor isn't something like x+1 or x-3 here we have x-y (2 variables) the best way to divide here is long division and i will walk you through this

Answer 8

Ok thank you so much

Answer 9

i hope that helps but since they said descending order i don't think it would matter here why? because both terms has a degree of 2. Bingo that's all you may ask for my help when you need me again :)

Answer 10

Thank you. I think when I have a problem that I can do the synthetic divisiojn with, ill try that.

Answer 11

do you remember the 1st problem we solved? go ahead and solve it yourself and i may have forgot to apply descending order so you may check that

Answer 12

Ok

Answer 13

no we solved it correctly just the last term edit it and put the divisor as denominator (just for the last term)
