Answer 1

(x-8)(x+1)

Answer 2

ohh duuhh haha

Answer 3

it goes along with your other problem therefore (x-8)s will cancel out

Answer 4

yeah they will
also is x^2-1 factorable?

Answer 5

its (x-1)(x+1)

Answer 6

just expand it to x^2 + 0x + 1 its easier to factor that way

Answer 7

i dont get that my teacher only taught us how to factor with 3 or more terms

Answer 8

oh ok thanks

Answer 9

no problem

Answer 10

i've cancelled the x-8 and the x+1 in my problem and now i have ((1)/(3x))X((4x^3)/(x-1)) is that simplified?

Answer 11

yeah that is the most simplified it can get
