Question

Hi sorry I didn’t post the problem I’m having trouble with the first couple.

Answer 1

Explanation:

#1

`(5x^2-5x)/(x^2-2x+1)\\(5x(x-1))/((x-1)(x-1))\\ (5x)/(x-1)`

#2

since it's negative, its npp (in the second part of the cubed factorization)

`((x-2)(x^2+2x+4))/((x^2-4))\\((x-2)(x^2+2x+4))/((x-2)(x+2))\\ \\((x^2+2x+4))/((x+2))\\`
