Not sure. Please explain the steps.

Answer 1

C. 2x-5

Explanation:

8x^3−10x^2−25x

4x^2+5x

=

8x^3−10x^2−25x

4x^2+5x

=

8x^2−10x−25

4x+5

=

(4x+5)(2x−5)

4x+5

=2x−5

Answer 2

answer C

Explanation:

hello

because this is not allowed to divide by 0 I would take x real different from 0 and from -5/4

`(8x^3-10x^2-25x)/(4x^2+5x)=(x(8x^2-10x-25))/(x(4x+5))=\\(8x^2-10x-25)/(4x+5)=((4x+5)(2x-5))/(4x+5)=2x-5`

indeed if we develop

`(4x+5)(2x-5)=8x^2-20x+10x-25=8x^2-10x-25`

hope this helps
