=(x-4)(x²+4x+16)

I Hope it's help you

Answer 2

Answer:

The answer is: x3+64=(x+4)(x2−4x+16).

Step-by-step explanation:

It's easy if we remember the formula of sum of cubes, that says:

x3+y3=(x+y)(x2−xy+y2).

In this case 64=43.

It's also to remember the formula of difference of cubes, that says:

x3−y3=(x−y)(x2+xy+y2).
