2x-y=66+x^{2}
Combine x and x to get 2x.
-y=66+x^{2}-2x
Subtract 2x from both sides.
-y=x^{2}-2x+66
The equation is in standard form.
\frac{-y}{-1}=\frac{x^{2}-2x+66}{-1}
Divide both sides by -1.
y=\frac{x^{2}-2x+66}{-1}
Dividing by -1 undoes the multiplication by -1.
y=-\left(x^{2}-2x+66\right)
Divide -2x+66+x^{2} by -1.
