Solve for y
y=2x\left(x+3\right)
Solve for x (complex solution)
x=\frac{\sqrt{2y+9}-3}{2}
x=\frac{-\sqrt{2y+9}-3}{2}
Solve for x
x=\frac{\sqrt{2y+9}-3}{2}
x=\frac{-\sqrt{2y+9}-3}{2}\text{, }y\geq -\frac{9}{2}

6x-y=-2x^{2}
Subtract 2x^{2} from both sides. Anything subtracted from zero gives its negation.
-y=-2x^{2}-6x
Subtract 6x from both sides.
\frac{-y}{-1}=-\frac{2x\left(x+3\right)}{-1}
Divide both sides by -1.
y=-\frac{2x\left(x+3\right)}{-1}
Dividing by -1 undoes the multiplication by -1.
y=2x\left(x+3\right)
Divide -2x\left(3+x\right) by -1.
