Question 986956: If 4g^2 +15 = 16h^2 -21 what is the value of g in terms of h?
I tried solving it:
4g^2 +15 = 16h^2 -21
-15 -15
_________________________
4g^2 = 16h^2 - 36
______ ____________
4 4
Simplify
Square root of g^2 = Square root of 4h^2 -36
g= Square root of 4h^2 -36.
Then, I did not know what to do next.

You can put this solution on YOUR website!
4g^2 +15 = 16h^2 -21
4g^2 = 16h^2 - 36
g^2 = 4h^2 - 9 *************** You didn't divide 36 by 4
g+=+sqrt%284h%5E2+-+9%29
That's all
