2mx+4m=-x^{2}
Subtract x^{2} from both sides. Anything subtracted from zero gives its negation.
\left(2x+4\right)m=-x^{2}
Combine all terms containing m.
\frac{\left(2x+4\right)m}{2x+4}=-\frac{x^{2}}{2x+4}
Divide both sides by 2x+4.
m=-\frac{x^{2}}{2x+4}
Dividing by 2x+4 undoes the multiplication by 2x+4.
m=-\frac{x^{2}}{2\left(x+2\right)}
Divide -x^{2} by 2x+4.
