SOLUTION: r^2-9=

Question 175030: r^2-9=
Answer by actuary(112) (Show Source): You can put this solution on YOUR website!
I suspect that you meant to write
r^2-9=0
The equation can be factored into (r+3)*(r-3)=0
So the solutions are r=3 and r=-3.
I hope that my interpretation of your question is correct. If not, just resubmit it.
