Solve for y
y=\frac{x^{2}-2x-5}{6}
Solve for x (complex solution)
x=\sqrt{6\left(y+1\right)}+1
x=-\sqrt{6\left(y+1\right)}+1
Solve for x
x=\sqrt{6\left(y+1\right)}+1
x=-\sqrt{6\left(y+1\right)}+1\text{, }y\geq -1

-2x-6y-5=-x^{2}
Subtract x^{2} from both sides. Anything subtracted from zero gives its negation.
-6y-5=-x^{2}+2x
Add 2x to both sides.
-6y=-x^{2}+2x+5
Add 5 to both sides.
-6y=5+2x-x^{2}
The equation is in standard form.
\frac{-6y}{-6}=\frac{5+2x-x^{2}}{-6}
Divide both sides by -6.
y=\frac{5+2x-x^{2}}{-6}
Dividing by -6 undoes the multiplication by -6.
y=\frac{x^{2}}{6}-\frac{x}{3}-\frac{5}{6}
Divide -x^{2}+2x+5 by -6.
