6x-y+9=-x^{2}
Subtract x^{2} from both sides. Anything subtracted from zero gives its negation.
-y+9=-x^{2}-6x
Subtract 6x from both sides.
-y=-x^{2}-6x-9
Subtract 9 from both sides.
\frac{-y}{-1}=-\frac{\left(x+3\right)^{2}}{-1}
Divide both sides by -1.
y=-\frac{\left(x+3\right)^{2}}{-1}
Dividing by -1 undoes the multiplication by -1.
y=\left(x+3\right)^{2}
Divide -\left(x+3\right)^{2} by -1.
