Simplifying
(x + -2(3))(x + -3(4)) = 5(24)

Multiply -2 * 3
(x + -6)(x + -3(4)) = 5(24)

Reorder the terms:
(-6 + x)(x + -3(4)) = 5(24)

Multiply -3 * 4
(-6 + x)(x + -12) = 5(24)

Reorder the terms:
(-6 + x)(-12 + x) = 5(24)

Multiply (-6 + x) * (-12 + x)
(-6(-12 + x) + x(-12 + x)) = 5(24)
((-12 * -6 + x * -6) + x(-12 + x)) = 5(24)
((72 + -6x) + x(-12 + x)) = 5(24)
(72 + -6x + (-12 * x + x * x)) = 5(24)
(72 + -6x + (-12x + x2)) = 5(24)

Combine like terms: -6x + -12x = -18x
(72 + -18x + x2) = 5(24)

Multiply 5 * 24
72 + -18x + x2 = 120

Solving
72 + -18x + x2 = 120

Solving for variable 'x'.

Reorder the terms:
72 + -120 + -18x + x2 = 120 + -120

Combine like terms: 72 + -120 = -48
-48 + -18x + x2 = 120 + -120

Combine like terms: 120 + -120 = 0
-48 + -18x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '48' to each side of the equation.
-48 + -18x + 48 + x2 = 0 + 48

Reorder the terms:
-48 + 48 + -18x + x2 = 0 + 48

Combine like terms: -48 + 48 = 0
0 + -18x + x2 = 0 + 48
-18x + x2 = 0 + 48

Combine like terms: 0 + 48 = 48
-18x + x2 = 48

The x term is -18x.  Take half its coefficient (-9).
