Solve for c 25=c^2

$25 = c^{2}$

Rewrite the equation as $c^{2} = 25$ .

$c^{2} = 25$

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

$c = \pm \sqrt{25}$

Simplify $\pm \sqrt{25}$ .

Rewrite $25$ as $5^{2}$ .

$c = \pm \sqrt{5^{2}}$

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

$c = \pm 5$

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.

$c = 5$

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

$c = - 5$

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

$c = 5, - 5$
