You can start by rewriting the equation so that the right side equals zero. Add

and

to both sides.

You can now use the quadratic equation (below), where

and

, to find solutions. Plug in these values for

and

into the equation and simplify.




The final answer is the combination of both solutions.

Or approximately...
