Simplifying X2 = (x + -2)(x + 2) Reorder the terms: X2 = (-2 + x)(x + 2) Reorder the terms: X2 = (-2 + x)(2 + x) Multiply (-2 + x) * (2 + x) X2 = (-2(2 + x) + x(2 + x)) X2 = ((2 * -2 + x * -2) + x(2 + x)) X2 = ((-4 + -2x) + x(2 + x)) X2 = (-4 + -2x + (2 * x + x * x)) X2 = (-4 + -2x + (2x + x2)) Combine like terms: -2x + 2x = 0 X2 = (-4 + 0 + x2) X2 = (-4 + x2) Solving X2 = -4 + x2 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Simplifying X2 = -4 + x2 Reorder the terms: 4 + X2 + -1x2 = -4 + x2 + 4 + -1x2 Reorder the terms: 4 + X2 + -1x2 = -4 + 4 + x2 + -1x2 Combine like terms: -4 + 4 = 0 4 + X2 + -1x2 = 0 + x2 + -1x2 4 + X2 + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 4 + X2 + -1x2 = 0 The solution to this equation could not be determined.
