Solve the following quadratic by
completing the square.
y = x² + 4x-2
x = [?] ± √ [ ]
Steps to Remember
1. Set the y-value equal to O.
2. Subtract the constant term from both sides.
3. Add ()² to both sides (to complete the square).
4. Factor (write as a perfect square).
5. Solve for x like normal.
