-3x + -2x + 5x2 + 2x2 = (7x + 4)(x + -3)

Combine like terms: -3x + -2x = -5x
-5x + 5x2 + 2x2 = (7x + 4)(x + -3)

Combine like terms: 5x2 + 2x2 = 7x2
-5x + 7x2 = (7x + 4)(x + -3)

Reorder the terms:
-5x + 7x2 = (4 + 7x)(x + -3)

Reorder the terms:
-5x + 7x2 = (4 + 7x)(-3 + x)

Multiply (4 + 7x) * (-3 + x)
-5x + 7x2 = (4(-3 + x) + 7x * (-3 + x))
-5x + 7x2 = ((-3 * 4 + x * 4) + 7x * (-3 + x))
-5x + 7x2 = ((-12 + 4x) + 7x * (-3 + x))
-5x + 7x2 = (-12 + 4x + (-3 * 7x + x * 7x))
-5x + 7x2 = (-12 + 4x + (-21x + 7x2))

Combine like terms: 4x + -21x = -17x
-5x + 7x2 = (-12 + -17x + 7x2)

Add '-7x2' to each side of the equation.
-5x + 7x2 + -7x2 = -12 + -17x + 7x2 + -7x2

Combine like terms: 7x2 + -7x2 = 0
-5x + 0 = -12 + -17x + 7x2 + -7x2
-5x = -12 + -17x + 7x2 + -7x2

Combine like terms: 7x2 + -7x2 = 0
-5x = -12 + -17x + 0
-5x = -12 + -17x
