-2x + -2x + 5x2 + 3x2 = (8x + 5)(x + -3)

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

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

Reorder the terms:
-4x + 8x2 = (5 + 8x)(x + -3)

Reorder the terms:
-4x + 8x2 = (5 + 8x)(-3 + x)

Multiply (5 + 8x) * (-3 + x)
-4x + 8x2 = (5(-3 + x) + 8x * (-3 + x))
-4x + 8x2 = ((-3 * 5 + x * 5) + 8x * (-3 + x))
-4x + 8x2 = ((-15 + 5x) + 8x * (-3 + x))
-4x + 8x2 = (-15 + 5x + (-3 * 8x + x * 8x))
-4x + 8x2 = (-15 + 5x + (-24x + 8x2))

Combine like terms: 5x + -24x = -19x
-4x + 8x2 = (-15 + -19x + 8x2)

Add '-8x2' to each side of the equation.
-4x + 8x2 + -8x2 = -15 + -19x + 8x2 + -8x2

Combine like terms: 8x2 + -8x2 = 0
-4x + 0 = -15 + -19x + 8x2 + -8x2
-4x = -15 + -19x + 8x2 + -8x2

Combine like terms: 8x2 + -8x2 = 0
-4x = -15 + -19x + 0
-4x = -15 + -19x
