Find the x-intercepts.

Tap for more steps...

To find the x-intercept(s), substitute in $0$ for $y$ and solve for $x$ .

$0 = x^{2}$

Solve the equation.

Tap for more steps...

Rewrite the equation as $x^{2} = 0$ .

$x^{2} = 0$

Take the square root of both sides of the equation to eliminate the exponent on the left side.

$x = \pm \sqrt{0}$

Simplify $\pm \sqrt{0}$ .

Rewrite $0$ as $0^{2}$ .

$x = \pm \sqrt{0^{2}}$

Pull terms out from under the radical, assuming positive real numbers.

$x = \pm 0$

Plus or minus $0$ is $0$ .

$x = 0$
