x2=484

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

x=±484

Simplify the right side of the equation.

Rewrite 484 as 222.

x=±222

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

x=±22

x=±22

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

First, use the positive value of the ± to find the first solution.

x=22

Next, use the negative value of the ± to find the second solution.

x=-22

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

x=22,-22

x=22,-22

x=22,-22

Solve using the Square Root Property x^2=484
