Simplifying x(x + 1)(x + 2) = 21 Reorder the terms: x(1 + x)(x + 2) = 21 Reorder the terms: x(1 + x)(2 + x) = 21 Multiply (1 + x) * (2 + x) x(1(2 + x) + x(2 + x)) = 21 x((2 * 1 + x * 1) + x(2 + x)) = 21 x((2 + 1x) + x(2 + x)) = 21 x(2 + 1x + (2 * x + x * x)) = 21 x(2 + 1x + (2x + x2)) = 21 Combine like terms: 1x + 2x = 3x x(2 + 3x + x2) = 21 (2 * x + 3x * x + x2 * x) = 21 (2x + 3x2 + x3) = 21 Solving 2x + 3x2 + x3 = 21 Solving for variable 'x'. Reorder the terms: -21 + 2x + 3x2 + x3 = 21 + -21 Combine like terms: 21 + -21 = 0 -21 + 2x + 3x2 + x3 = 0 The solution to this equation could not be determined.
