Solve Using the Square Root Property y^2=196

$y^{2} = 196$

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

$y = \pm \sqrt{196}$

Simplify $\pm \sqrt{196}$ .

Rewrite $196$ as $14^{2}$ .

$y = \pm \sqrt{14^{2}}$

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

$y = \pm 14$

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.

$y = 14$

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

$y = - 14$

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

$y = 14, - 14$
