The square root method involves taking the square root of both sides of the equation. Since $y^2 = 5$, taking the square root of both sides gives $y = \pm \sqrt{5}$, because both positive and negative roots are solutions to the original equation.

Use the Square Root Method to - y2=5y ^ { 2 } = 5y2=5

Use the Square Root Method to
- $y ^ { 2 } = 5$
