how do I solve this equation? x(x+2)(x-2)(x-5)

OpenStudy (anonymous):

like how do i simplify it

OpenStudy (anonymous):

You distribute.

OpenStudy (jdoe0001):

hmm... simplify it? looks very simplified to me

OpenStudy (anonymous):

like my teacher gave us the answer, its \[x ^{4}-5x ^{3}-4x ^{2}+20x\] but i dont understand how she got that

OpenStudy (jdoe0001):

well... I'd say that's not really simplified... just the "standard form" of it, but you'd get to that by just multiplying all the factors

OpenStudy (anonymous):

2x3−13x2+20x

OpenStudy (anonymous):

like we are supposed to go from factored form to general form

OpenStudy (jdoe0001):

yeap

OpenStudy (anonymous):

i dont know where the numbers are coming from but i understand how she got \[x^{4}\]

OpenStudy (anonymous):

You combine like terms, and you have to distribute and multiply.

OpenStudy (jdoe0001):

you multiply all the binomials

OpenStudy (anonymous):

can you take me through the steps on how to do that?

OpenStudy (jdoe0001):

\(\bf (a+b)(c+d)\implies a\cdot (c+d)+b\cdot (c+d)\)
