RhondaSommer (rhondasommer):
replace the x in f(x) with g(x) equation
OpenStudy (anonymous):

-3x but yeah

RhondaSommer (rhondasommer):
so now you are looking for the numbers that make g(x) equal to zero
OpenStudy (anonymous):
wait if it's 3x wouldn't it be -3*1/x ? :(
RhondaSommer (rhondasommer):
-1 * 3x
RhondaSommer (rhondasommer):
that's irrelevant though; \[1\div x^2 - 3x\] is your equation
OpenStudy (anonymous):
And where do I go from there?:/

so your answers are...
OpenStudy (anonymous):
0,3 or would I separate them with a space?
OpenStudy (anonymous):
Nevermind it says comma so 0,3
RhondaSommer (rhondasommer):
