Simplifying (x + -2)(x2 + 2x + -1) = 4(x + 1) Reorder the terms: (-2 + x)(x2 + 2x + -1) = 4(x + 1) Reorder the terms: (-2 + x)(-1 + 2x + x2) = 4(x + 1) Multiply (-2 + x) * (-1 + 2x + x2) (-2(-1 + 2x + x2) + x(-1 + 2x + x2)) = 4(x + 1) ((-1 * -2 + 2x * -2 + x2 * -2) + x(-1 + 2x + x2)) = 4(x + 1) ((2 + -4x + -2x2) + x(-1 + 2x + x2)) = 4(x + 1) (2 + -4x + -2x2 + (-1 * x + 2x * x + x2 * x)) = 4(x + 1) (2 + -4x + -2x2 + (-1x + 2x2 + x3)) = 4(x + 1) Reorder the terms: (2 + -4x + -1x + -2x2 + 2x2 + x3) = 4(x + 1) Combine like terms: -4x + -1x = -5x (2 + -5x + -2x2 + 2x2 + x3) = 4(x + 1) Combine like terms: -2x2 + 2x2 = 0 (2 + -5x + 0 + x3) = 4(x + 1) (2 + -5x + x3) = 4(x + 1) Reorder the terms: 2 + -5x + x3 = 4(1 + x) 2 + -5x + x3 = (1 * 4 + x * 4) 2 + -5x + x3 = (4 + 4x) Solving 2 + -5x + x3 = 4 + 4x Solving for variable 'x'. Reorder the terms: 2 + -4 + -5x + -4x + x3 = 4 + 4x + -4 + -4x Combine like terms: 2 + -4 = -2 -2 + -5x + -4x + x3 = 4 + 4x + -4 + -4x Combine like terms: -5x + -4x = -9x -2 + -9x + x3 = 4 + 4x + -4 + -4x Reorder the terms: -2 + -9x + x3 = 4 + -4 + 4x + -4x Combine like terms: 4 + -4 = 0 -2 + -9x + x3 = 0 + 4x + -4x -2 + -9x + x3 = 4x + -4x Combine like terms: 4x + -4x = 0 -2 + -9x + x3 = 0 The solution to this equation could not be determined.
