Question 421435: I am homeschooled and I have worked on this problem for hours. My mom finally gave me the answer but I don't seem to know how to do the steps correctly to get the answer. If I put my work in here it would take up all the space, so here is the question and the answer. I need the steps.
25x^2 - 40xy + 16y^2, Again I know the answer is (5x - 4y)^2 but I can't get the steps.

25x^2 - 40xy + 16y^2,
25x^2-20xy-20xy+16y^2
5x(5x-4y)-4y(5x-4y)
(5x-4y)(5x-4y)
(5x-4y)^2
