Solving a Quadratic Equation When a ≠ 1 by Completing the Square Consider 8x2 - 48x = -104.

Write the equation so that

a = 1: x2 + _ x= _

Complete the square:

x2 – 6x + _ = –13 + _

Factor the trinomial and simplify:

(x +___ )² = _

Use the square root property of equality to solve
(x – 3)2 = –4.

The solutions are_
