First terms:
(x^2 - 5x)(5x - 25)

5x3 - 25x2 25x2 + 125x

Through distribution

Explanation:

First take x2 * 5x, then x2 * -25, after distributing the x2 do the same with the -5x in the first parenthesis. After getting your solutions ( 5x3+ 25x2- 10x2+125x) you can simplify. Adding the 25x2 and the 10x2 getting 35x2.
