Multiply: (x^2 − 5x)(5x − 25)

OpenStudy (anonymous):

my answer was 5x(x-5)(x-5) and its wrong :(

OpenStudy (chriss):

5x^3-50x^2-125x

OpenStudy (anonymous):

you first need to do the distributive property.

OpenStudy (anonymous):

you can simply apply foil: 5x^3-25x^2-25x^2+125x, then just gather like term

OpenStudy (anonymous):

i did a foil type thing to start of and i got he same part as chris

OpenStudy (chriss):

+125x... sorry

OpenStudy (anonymous):

then i took a 5x out and got 5x(x^2-10x+25)

OpenStudy (anonymous):

then i got 5x(x-5)(x-5)

OpenStudy (chriss):

was the final answer supposed to be factored?

OpenStudy (anonymous):

it gives you the simplified answer, you must multiply it out

OpenStudy (anonymous):

and not simplify

OpenStudy (anonymous):

it just says to multiply

OpenStudy (anonymous):

5x^3-25x^2-25x^2+125x, was it? lol

OpenStudy (anonymous):

it implies that it doesn't want the simplified form

OpenStudy (chriss):

then I would answer with the 3rd degree polynomial

OpenStudy (anonymous):

i mean 5x^3-50x^2+125x

OpenStudy (anonymous):

ok ill try it out

OpenStudy (anonymous):

yay its correct, thanks fellas!

OpenStudy (chriss):
