Simplifying 0 = (x + -2)(x2 + -9) Reorder the terms: 0 = (-2 + x)(x2 + -9) Reorder the terms: 0 = (-2 + x)(-9 + x2) Multiply (-2 + x) * (-9 + x2) 0 = (-2(-9 + x2) + x(-9 + x2)) 0 = ((-9 * -2 + x2 * -2) + x(-9 + x2)) 0 = ((18 + -2x2) + x(-9 + x2)) 0 = (18 + -2x2 + (-9 * x + x2 * x)) 0 = (18 + -2x2 + (-9x + x3)) Reorder the terms: 0 = (18 + -9x + -2x2 + x3) 0 = (18 + -9x + -2x2 + x3) Solving 0 = 18 + -9x + -2x2 + x3 Solving for variable 'x'. Combine like terms: 0 + -18 = -18 -18 + 9x + 2x2 + -1x3 = 18 + -9x + -2x2 + x3 + -18 + 9x + 2x2 + -1x3 Reorder the terms: -18 + 9x + 2x2 + -1x3 = 18 + -18 + -9x + 9x + -2x2 + 2x2 + x3 + -1x3 Combine like terms: 18 + -18 = 0 -18 + 9x + 2x2 + -1x3 = 0 + -9x + 9x + -2x2 + 2x2 + x3 + -1x3 -18 + 9x + 2x2 + -1x3 = -9x + 9x + -2x2 + 2x2 + x3 + -1x3 Combine like terms: -9x + 9x = 0 -18 + 9x + 2x2 + -1x3 = 0 + -2x2 + 2x2 + x3 + -1x3 -18 + 9x + 2x2 + -1x3 = -2x2 + 2x2 + x3 + -1x3 Combine like terms: -2x2 + 2x2 = 0 -18 + 9x + 2x2 + -1x3 = 0 + x3 + -1x3 -18 + 9x + 2x2 + -1x3 = x3 + -1x3 Combine like terms: x3 + -1x3 = 0 -18 + 9x + 2x2 + -1x3 = 0 The solution to this equation could not be determined.
