You can put this solution on YOUR website!
p-mg=m%5E2%2Fy
py-ymg=m%5E2
m%5E2%2Bmyg=py
m%5E2-ygm-py=0
Some steps were combined.

m=%28yg%2B-+sqrt%28y%5E2%2Ag%5E2-4%2A%28-py%29%29%29%2F2
highlight%28m=%28yg%2B-+sqrt%28%28yg%29%5E2%2B4py%29%29%2F2%29


THAT is as simple as possible. The formula obtained for m is based on a quadratic equation which is not factorable without other suitable information, so you can only rely on the general solution for a quadratic equation.
