I was working on the difference of two squares, 125p2−45q2
Writing my answer, (5√5p−3√5q)(5√5p+3√5q), onto Pearson, I got a popup that said my answer was equivalent to the correct answer but in incorrect form. Apparently, the correct answer is 5(5p−3q)(5p+3q).
Why is that? I'm failing to see the intuition here.
