Simplifying
0 = (11x + 5)(-11x + 12)

Reorder the terms:
0 = (5 + 11x)(-11x + 12)

Reorder the terms:
0 = (5 + 11x)(12 + -11x)

Multiply (5 + 11x) * (12 + -11x)
0 = (5(12 + -11x) + 11x * (12 + -11x))
0 = ((12 * 5 + -11x * 5) + 11x * (12 + -11x))
0 = ((60 + -55x) + 11x * (12 + -11x))
0 = (60 + -55x + (12 * 11x + -11x * 11x))
0 = (60 + -55x + (132x + -121x2))

Combine like terms: -55x + 132x = 77x
0 = (60 + 77x + -121x2)
