Question

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

Answer 1

like how do i simplify it

Answer 2

You distribute.

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

2x3−13x2+20x

Answer 7

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

Answer 8

yeap

Answer 9

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

Answer 10

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

Answer 11

you multiply all the binomials

Answer 12

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

Answer 13

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