@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

how do i factor that? like what do i do first? @satellite73
OpenStudy (mikezack123):
thanks! :) @jada1701877

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 ?

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
