Simplifying 2x(2x + 2) = 4x + -4 Reorder the terms: 2x(2 + 2x) = 4x + -4 (2 * 2x + 2x * 2x) = 4x + -4 (4x + 4x2) = 4x + -4 Reorder the terms: 4x + 4x2 = -4 + 4x Add '-4x' to each side of the equation. 4x + -4x + 4x2 = -4 + 4x + -4x Combine like terms: 4x + -4x = 0 0 + 4x2 = -4 + 4x + -4x 4x2 = -4 + 4x + -4x Combine like terms: 4x + -4x = 0 4x2 = -4 + 0 4x2 = -4 Solving 4x2 = -4 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Divide each side by '4'. x2 = -1 Simplifying x2 = -1 Reorder the terms: 1 + x2 = -1 + 1 Combine like terms: -1 + 1 = 0 1 + x2 = 0 The solution to this equation could not be determined.
