Best ResponseYou've already chosen the best response.0OK... first of all look at the first polynomial... look at their exponents. you see. x^5 then x^3 then x^2 then x then 2 Do you see that x^4 is missing?

Best ResponseYou've already chosen the best response.0OK we will have to put in 0 of those because that is how this works. Also... in the x^2 + 2x  3 nothing is missing because we have x^2 and 2x OK.. here we go.

Best ResponseYou've already chosen the best response.0 x^2 + 2x  3  2x^5 + 0x^4 + 4x^3  5x^2 + 3x  2 what do we need to multiply x^2 by to get 2x^5?

Best ResponseYou've already chosen the best response.0Good... 2x^3  x^2 + 2x  3  2x^5 + 0x^4 + 4x^3  5x^2 + 3x  2 as soon as you enter a number up top you multiply it by everything on the left .. you distribute

Best ResponseYou've already chosen the best response.02x^3  x^2 + 2x  3  2x^5 + 0x^4 + 4x^3  5x^2 + 3x  2 2x^5 + 4x^4  6x^3  OK?

Best ResponseYou've already chosen the best response.0Once you multiply... (distribute) you draw a line and then change the signs of every term on the bottom and then add the terms and then bring down the next term. 2x^3  x^2 + 2x  3  2x^5 + 0x^4 + 4x^3  5x^2 + 3x  2  2x^5  4x^4 + 6x^3  4x^4 + 10x^3  5x^2 OK? and then we do the process again (notice that I changed every term on the polynomial before I added.)

Best ResponseYou've already chosen the best response.02x^3  x^2 + 2x  3  2x^5 + 0x^4 + 4x^3  5x^2 + 3x  2  2x^5  4x^4 + 6x^3  4x^4 + 10x^3  5x^2 What do you need to multiply x^2 by to get 4x^4?

Best ResponseYou've already chosen the best response.02x^3  2x^2  x^2 + 2x  3  2x^5 + 0x^4 + 4x^3  5x^2 + 3x  2  2x^5  4x^4 + 6x^3  4x^4 + 10x^3  5x^2 4x^4  4x^3 + 6x^2  No.. 2x^2 you need the  sign. So I multiplied, drew the line, now change every sign on the bottom, add and bring down the next term.

Best ResponseYou've already chosen the best response.02x^3  2x^2 + 14x  29 R. 103x  89  x^2 + 2x  3  2x^5 + 0x^4 + 4x^3  5x^2 + 3x  2  2x^5  4x^4 + 6x^3  4x^4 + 10x^3  5x^2 +4x^4 + 4x^3  6x^2  14x^3  x^2 + 3x 14x^3  28x^2 + 42x  29x^2 + 45x  2 +29x^2 + 58x  87  103x  89 Now x^2 times what is 14x^3 answer + 14x I put that on top, multiplied, drew the line, changed the signs, added, brought down the next term. Now x^2 times what is 29x^2 answer 29 I put that on top, multiplied, drew the line, changed the signs, added, brought down the next term Then what is leftover is the remainder. Do you understand?
