Problem

x2=121

Solution

1. Identify the equation as a quadratic in the form x2=k where k is a constant.

2. Apply the square root property by taking the square root of both sides of the equation.

3. Include both roots by adding a plus-or-minus sign (± to the square root of the constant.

x=±√(,121)

4. Simplify the square root of 121 since 11×11=121
