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

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

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

Reorder the terms:
-8x + 4x2 = (6 + 4x)(x + -5)

Reorder the terms:
-8x + 4x2 = (6 + 4x)(-5 + x)

Multiply (6 + 4x) * (-5 + x)
-8x + 4x2 = (6(-5 + x) + 4x * (-5 + x))
-8x + 4x2 = ((-5 * 6 + x * 6) + 4x * (-5 + x))
-8x + 4x2 = ((-30 + 6x) + 4x * (-5 + x))
-8x + 4x2 = (-30 + 6x + (-5 * 4x + x * 4x))
-8x + 4x2 = (-30 + 6x + (-20x + 4x2))

Combine like terms: 6x + -20x = -14x
-8x + 4x2 = (-30 + -14x + 4x2)

Add '-4x2' to each side of the equation.
-8x + 4x2 + -4x2 = -30 + -14x + 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
-8x + 0 = -30 + -14x + 4x2 + -4x2
-8x = -30 + -14x + 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
-8x = -30 + -14x + 0
-8x = -30 + -14x

Solving
-8x = -30 + -14x

Solving for variable 'x'.
