Question 139933: I have a homework problem that I can't seem to solve, could I have some help...thank you. m^2+6m-9=0. I have tried and can't figure it out.

m^2+6m-9=0
m^2+6m =9
m^2+6m+9=9+9 completing the square by dividing the 2nd term by 2 and squaring the result.
(m+3)^2=18
m+3=+-sqrt(9*2)
m=-3+3sqrt(2), m=-3-3sqrt(2)
