-4x + -4x + 2x2 + 4x2 = (6x + 5)(x + -3)

Combine like terms: -4x + -4x = -8x
-8x + 2x2 + 4x2 = (6x + 5)(x + -3)

Combine like terms: 2x2 + 4x2 = 6x2
-8x + 6x2 = (6x + 5)(x + -3)

Reorder the terms:
-8x + 6x2 = (5 + 6x)(x + -3)

Reorder the terms:
-8x + 6x2 = (5 + 6x)(-3 + x)

Multiply (5 + 6x) * (-3 + x)
-8x + 6x2 = (5(-3 + x) + 6x * (-3 + x))
-8x + 6x2 = ((-3 * 5 + x * 5) + 6x * (-3 + x))
-8x + 6x2 = ((-15 + 5x) + 6x * (-3 + x))
-8x + 6x2 = (-15 + 5x + (-3 * 6x + x * 6x))
-8x + 6x2 = (-15 + 5x + (-18x + 6x2))

Combine like terms: 5x + -18x = -13x
-8x + 6x2 = (-15 + -13x + 6x2)

Add '-6x2' to each side of the equation.
-8x + 6x2 + -6x2 = -15 + -13x + 6x2 + -6x2

Combine like terms: 6x2 + -6x2 = 0
-8x + 0 = -15 + -13x + 6x2 + -6x2
-8x = -15 + -13x + 6x2 + -6x2

Combine like terms: 6x2 + -6x2 = 0
-8x = -15 + -13x + 0
-8x = -15 + -13x
