361=x2

Rewrite the equation as x2=361.

x2=361

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

x=±361

Simplify the right side of the equation.

Rewrite 361 as 192.

x=±192

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

x=±19

x=±19

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=19

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

x=-19

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

x=19,-19

x=19,-19

x=19,-19

Solve using the Square Root Property 361=x^2
