Solve x^2-4y=0

$$x ^ { 2 } - 4 y = 0$$

Solve for y

$$y=\frac{x^{2}}{4}$$

Steps for Solving Linear Equation

Subtract x^{2} from both sides. Anything subtracted from zero gives its negation.

$$-4y=-x^{2}$$

Divide both sides by -4.

$$\frac{-4y}{-4}=-\frac{x^{2}}{-4}$$

Dividing by -4 undoes the multiplication by -4.

$$y=-\frac{x^{2}}{-4}$$

Divide -x^{2} by -4.

$$y=\frac{x^{2}}{4}$$

Solve for x (complex solution)

$$x=-2\sqrt{y}$$

$$x=2\sqrt{y}$$

Solve for x

$$x=2\sqrt{y}$$

$$x=-2\sqrt{y}\text{, }y\geq 0$$
