You distribute.

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

anonymous · Answer

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

jdoe0001 · Answer

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

anonymous · Answer

2x3−13x2+20x

anonymous · Answer

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

jdoe0001 · Answer

yeap

anonymous · Answer

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

anonymous · Answer

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

jdoe0001 · Answer

you multiply all the binomials

anonymous · Answer

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

jdoe0001 · Answer

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