Question

(x+9)(x-6) > 0

Answer 1

@EulerGroupie Already showed us how to do this... When it is equal to 0?

Answer 2

If either factor is 0, then it multiplied out to 0.

Answer 3

\[x^2+(9-6)x-54>0\]
then solve it

Answer 4

@MBrecht92 ok

Answer 5

So \[x+9=0\]\[x-6=0\]It's just solving for x to get critical points... then testing between those points.
