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

-y=1-5x^{2}
Subtract 5x^{2} from both sides.
\frac{-y}{-1}=\frac{1-5x^{2}}{-1}
Divide both sides by -1.
y=\frac{1-5x^{2}}{-1}
Dividing by -1 undoes the multiplication by -1.
y=5x^{2}-1
Divide 1-5x^{2} by -1.
