Solve the Inequality for x x^2<3

$x^{2} < 3$

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

$\sqrt{x^{2}} < \sqrt{3}$

Simplify the left side.

Pull terms out from under the radical.

$| x | < \sqrt{3}$

Write $| x | < \sqrt{3}$ as a piecewise.

To find the interval for the first piece, find where the inside of the absolute value is non-negative.

$x \geq 0$

In the piece where $x$ is non-negative, remove the absolute value.

$x < \sqrt{3}$

To find the interval for the second piece, find where the inside of the absolute value is negative.

$x < 0$

In the piece where $x$ is negative, remove the absolute value and multiply by $- 1$ .

$- x < \sqrt{3}$

Write as a piecewise.

${\begin{cases} x < \sqrt{3} & x \geq 0 \\ - x < \sqrt{3} & x < 0 \end{cases}$

Find the intersection of $x < \sqrt{3}$ and $x \geq 0$ .

$0 \leq x < \sqrt{3}$

Solve $- x < \sqrt{3}$ when $x < 0$ .

Divide each term in $- x < \sqrt{3}$ by $- 1$ and simplify.

Divide each term in $- x < \sqrt{3}$ by $- 1$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$\frac{- x}{- 1} > \frac{\sqrt{3}}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{x}{1} > \frac{\sqrt{3}}{- 1}$

Divide $x$ by $1$ .

$x > \frac{\sqrt{3}}{- 1}$

Simplify the right side.

Move the negative one from the denominator of $\frac{\sqrt{3}}{- 1}$ .

$x > - 1 \cdot \sqrt{3}$

Rewrite $- 1 \cdot \sqrt{3}$ as $- \sqrt{3}$ .

$x > - \sqrt{3}$

Find the intersection of $x > - \sqrt{3}$ and $x < 0$ .

$- \sqrt{3} < x < 0$

Find the union of the solutions.

$- \sqrt{3} < x < \sqrt{3}$

The result can be shown in multiple forms.

Inequality Form:

$- \sqrt{3} < x < \sqrt{3}$

Interval Notation:

$(- \sqrt{3}, \sqrt{3})$
