-2x + -7x + 2x2 + 2x2 = (4x + 9)(x + -6)

Combine like terms: -2x + -7x = -9x
-9x + 2x2 + 2x2 = (4x + 9)(x + -6)

Combine like terms: 2x2 + 2x2 = 4x2
-9x + 4x2 = (4x + 9)(x + -6)

Reorder the terms:
-9x + 4x2 = (9 + 4x)(x + -6)

Reorder the terms:
-9x + 4x2 = (9 + 4x)(-6 + x)

Multiply (9 + 4x) * (-6 + x)
-9x + 4x2 = (9(-6 + x) + 4x * (-6 + x))
-9x + 4x2 = ((-6 * 9 + x * 9) + 4x * (-6 + x))
-9x + 4x2 = ((-54 + 9x) + 4x * (-6 + x))
-9x + 4x2 = (-54 + 9x + (-6 * 4x + x * 4x))
-9x + 4x2 = (-54 + 9x + (-24x + 4x2))

Combine like terms: 9x + -24x = -15x
-9x + 4x2 = (-54 + -15x + 4x2)

Add '-4x2' to each side of the equation.
-9x + 4x2 + -4x2 = -54 + -15x + 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
-9x + 0 = -54 + -15x + 4x2 + -4x2
-9x = -54 + -15x + 4x2 + -4x2
