Solve y^2-8x=0

$$y ^ { 2 } - 8 x = 0$$

Solve for x

$$x=\frac{y^{2}}{8}$$

Steps for Solving Linear Equation

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

$$-8x=-y^{2}$$

Divide both sides by -8.

$$\frac{-8x}{-8}=-\frac{y^{2}}{-8}$$

Dividing by -8 undoes the multiplication by -8.

$$x=-\frac{y^{2}}{-8}$$

Divide -y^{2} by -8.

$$x=\frac{y^{2}}{8}$$

Solve for y (complex solution)

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

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

Solve for y

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

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