Question

I need answers for these equations?

Answer 1

Explanation:

Simple

8x4 + 8x3 + 27x + 27

First there is 8 common on one side and 27 on another

So

8x3 ( x + 1) + 27 ( x + 1)

(8x3 + 27) and (x + 1) are the factors

3 2x3 - 32x2 + 120x - 1920

2x2 ( x - 16) + 120 (x - 16)

(x - 16) and ( 2x2 + 120) are the factors

Hope you have understood and will do the second one
