1 Solve x 2 − 20 = 0. 2 Solve z 2 + 7 = 0. 3 Solve (p + 5)2 = 49. Applications Outline Quadratic Equations Solving Quadratic Equations Applications Completing the Square
We can put a quadratic equation of the form
ax 2 + bx + c = 0 (a = 0) into the form (x − h)2 = k for some
constants h and k by completing the square.

x 2 + b1 + c1 = 0.
Subtract c1 from both sides.
