Solve Using the Square Root Property x^2=169

Problem

x2=169

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 constant side to account for both positive and negative solutions.

x=±√(,169)

4. Simplify the square root of 169 which is 13

x=±13

Final Answer

x=±13
