L^{2}=x-q
Multiply L and L to get L^{2}.
x-q=L^{2}
Swap sides so that all variable terms are on the left hand side.
-q=L^{2}-x
Subtract x from both sides.
\frac{-q}{-1}=\frac{L^{2}-x}{-1}
Divide both sides by -1.
q=\frac{L^{2}-x}{-1}
Dividing by -1 undoes the multiplication by -1.
q=x-L^{2}
Divide L^{2}-x by -1.
