Step 2.1

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

$X = \sqrt{19}$

Step 2.2

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

$X = - \sqrt{19}$

Step 2.3

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:

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