By taking x as common and then applying middle term splitting

Explanation:

First, take xx and 5 5 as common:
5x^3-20x^2+20x5x320x2+20x
=5x(x^2-4x+4)=5x(x24x+4)

Then by middle term splitting:
=5x(x^2-4x+4)=5x(x24x+4)
=5x(x^2-2x-2x+4)=5x(x22x2x+4)
=5x(x(x-2)-2(x-2))=5x(x(x2)2(x2))
=5x(x-2)^2=5x(x2)2
