is x^2-7x-8 factorable?

OpenStudy (anonymous):

(x-8)(x+1)

OpenStudy (anonymous):

ohh duuhh haha

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

its (x-1)(x+1)

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

oh ok thanks

OpenStudy (anonymous):

no problem

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

yeah that is the most simplified it can get
