-2x + 2x2 + x(-2 + 5x) = (7x + 8)(x + -2)
-2x + 2x2 + (-2 * x + 5x * x) = (7x + 8)(x + -2)
-2x + 2x2 + (-2x + 5x2) = (7x + 8)(x + -2)

Reorder the terms:
-2x + -2x + 2x2 + 5x2 = (7x + 8)(x + -2)

Combine like terms: -2x + -2x = -4x
-4x + 2x2 + 5x2 = (7x + 8)(x + -2)

Combine like terms: 2x2 + 5x2 = 7x2
-4x + 7x2 = (7x + 8)(x + -2)

Reorder the terms:
-4x + 7x2 = (8 + 7x)(x + -2)

Reorder the terms:
-4x + 7x2 = (8 + 7x)(-2 + x)

Multiply (8 + 7x) * (-2 + x)
-4x + 7x2 = (8(-2 + x) + 7x * (-2 + x))
-4x + 7x2 = ((-2 * 8 + x * 8) + 7x * (-2 + x))
-4x + 7x2 = ((-16 + 8x) + 7x * (-2 + x))
-4x + 7x2 = (-16 + 8x + (-2 * 7x + x * 7x))
-4x + 7x2 = (-16 + 8x + (-14x + 7x2))

Combine like terms: 8x + -14x = -6x
-4x + 7x2 = (-16 + -6x + 7x2)

Add '-7x2' to each side of the equation.
-4x + 7x2 + -7x2 = -16 + -6x + 7x2 + -7x2

Combine like terms: 7x2 + -7x2 = 0
-4x + 0 = -16 + -6x + 7x2 + -7x2
-4x = -16 + -6x + 7x2 + -7x2

Combine like terms: 7x2 + -7x2 = 0
-4x = -16 + -6x + 0
-4x = -16 + -6x

Solving
-4x = -16 + -6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.
