multiply (x-4)(x^2-5x-6)

OpenStudy (amistre64):

how would you go about this?

OpenStudy (anonymous):

multipy each term in the first with each term in the second, then combine like items

OpenStudy (anonymous):

first, mult x with (x^2-5x-6)

OpenStudy (anonymous):

oh yea that's right, thanks

OpenStudy (amistre64):

i tend to get confused tracking terms; so I just stack them and multiply like normal numbers :)

OpenStudy (anonymous):

You want to distribute each term to every term in the parenteses. So you get X^3-5x^2-6x-4x^2-20x-24

OpenStudy (anonymous):

*** +20x+24 ***

OpenStudy (anonymous):

not Negative

OpenStudy (anonymous):

haha thanks

OpenStudy (amistre64):

x^2-5x-6 x-4 ---------- x^3 -5x^2 -6x -4x^2+20x+24 ------------------ x^3 -9x^2 +14x + 24

I didn't combine my like terms, I figured you could do that, but my answer is just as good!!!!

OpenStudy (amistre64):

OpenStudy (amistre64):
