@jada1701877 thanks but why'd you give me a medal? lol

OpenStudy (anonymous):

factor and cancel

OpenStudy (anonymous):

\[\frac{(x+3)(x-3)}{x(x-3)}\] is a start

OpenStudy (anonymous):

Because that looks confusing and at least you asked for help. Tbh some people don't even ask for help. They just fail

OpenStudy (mikezack123):

how do i factor that? like what do i do first? @satellite73

OpenStudy (mikezack123):

thanks! :) @jada1701877

OpenStudy (anonymous):

i factored it for you the top factors because it is the difference of two squares \[a^2-b^2=(a+b)(a-b)\] so \[x^2-9=(x+3)(x-3)\]

OpenStudy (anonymous):

the denominator factors because each term has a common factor of \(x\) making \[x^2-3x=x(x-3)\]

OpenStudy (mikezack123):

then we subtract x^2 ?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

\[\frac{x^2-9}{x^2-3x}=\frac{(x+3)(x-3)}{x(x-3)}\]

OpenStudy (anonymous):

then cancel the common factor of \(x-3\) top and bottom

OpenStudy (mikezack123):

x^2-9 / x^2-3x = (x+3)/x

OpenStudy (anonymous):

yes

OpenStudy (mikezack123):

Thank you! @satellite73 :) :) :)
