For this case we must find the value of "x" of the following equation:

x ^ 2-9 = 0

So:

We add 9 to both sides of the equation:

$x ^ 2-9 + 9 = 9\\x ^ 2 = 9$

We apply square root on both sides of the equation to eliminate the exponent on the left side:

$x = \pm \sqrt {9}$

Thus, the solutions are:

$x_ {1} = + 3\\x_ {2} = - 3$
