Solve Using the Square Root Property X^2=19

$X^{2} = 19$

Step 1

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

$X = \pm \sqrt{19}$

Step 2

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the $\pm$ to find the first solution.

$X = \sqrt{19}$

Next, use the negative value of the $\pm$ to find the second solution.

$X = - \sqrt{19}$

The complete solution is the result of both the positive and negative portions of the solution.

$X = \sqrt{19}, - \sqrt{19}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$X = \sqrt{19}, - \sqrt{19}$

Decimal Form:

$X = 4.35889894 \dots, - 4.35889894 \dots$
