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

Reorder the terms:
-5x + 2x2 = (6 + 2x)(x + -4)

Reorder the terms:
-5x + 2x2 = (6 + 2x)(-4 + x)

Multiply (6 + 2x) * (-4 + x)
-5x + 2x2 = (6(-4 + x) + 2x * (-4 + x))
-5x + 2x2 = ((-4 * 6 + x * 6) + 2x * (-4 + x))
-5x + 2x2 = ((-24 + 6x) + 2x * (-4 + x))
-5x + 2x2 = (-24 + 6x + (-4 * 2x + x * 2x))
-5x + 2x2 = (-24 + 6x + (-8x + 2x2))
