x^{2}=y
Swap sides so that all variable terms are on the left hand side.
x=\sqrt{y} x=-\sqrt{y}
Take the square root of both sides of the equation.
x^{2}=y
Swap sides so that all variable terms are on the left hand side.
x^{2}-y=0
Subtract y from both sides.
x=\frac{0±\sqrt{0^{2}-4\left(-y\right)}}{2}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and -y for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\left(-y\right)}}{2}
Square 0.
x=\frac{0±\sqrt{4y}}{2}
Multiply -4 times -y.
x=\frac{0±2\sqrt{y}}{2}
Take the square root of 4y.
x=\sqrt{y}
Now solve the equation x=\frac{0±2\sqrt{y}}{2} when ± is plus.
x=-\sqrt{y}
Now solve the equation x=\frac{0±2\sqrt{y}}{2} when ± is minus.
x=\sqrt{y} x=-\sqrt{y}
The equation is now solved.
