my answer was 5x(x-5)(x-5) and its wrong :(
5x^3-50x^2-125x
you first need to do the distributive property.
you can simply apply foil: 5x^3-25x^2-25x^2+125x, then just gather like term
i did a foil type thing to start of and i got he same part as chris

+125x... sorry
then i took a 5x out and got 5x(x^2-10x+25)
then i got 5x(x-5)(x-5)
was the final answer supposed to be factored?
it gives you the simplified answer, you must multiply it out

and not simplify
it just says to multiply
5x^3-25x^2-25x^2+125x, was it? lol
it implies that it doesn't want the simplified form
then I would answer with the 3rd degree polynomial
