Question

-m^2=-81

Answer 1

If your aim is to find what m equals then this is quite simple. So we take (-m^2) and -81 from both sides to get

m^2=81

Now root both sides to get rid of the ^2 and we get

m=9

Answer 2

divide both sides of the equation by -1

then take the square root of both sides

m will have 2 solutions
