Answer:

(2x-5)(4x^2+10x+25)

Explanation:

Factoring difference of cubes (a3−b3): (a−b)(a2+ab+b2)

Here, a is 2x because the cube root of 8 is 2 and the cube root of x3 is x, b is 5 because the cube root of 125 is 5.

Plug the numbers in:

(2x−5)((2x)2+2x⋅5+52)

(2x−5)(22x2+10x+25)

(2x−5)(4x2+10x+25)
