Simplifying (4x3 + 8x)(x2 + -1) = 0 Reorder the terms: (8x + 4x3)(x2 + -1) = 0 Reorder the terms: (8x + 4x3)(-1 + x2) = 0 Multiply (8x + 4x3) * (-1 + x2) (8x * (-1 + x2) + 4x3 * (-1 + x2)) = 0 ((-1 * 8x + x2 * 8x) + 4x3 * (-1 + x2)) = 0 ((-8x + 8x3) + 4x3 * (-1 + x2)) = 0 (-8x + 8x3 + (-1 * 4x3 + x2 * 4x3)) = 0 (-8x + 8x3 + (-4x3 + 4x5)) = 0 Combine like terms: 8x3 + -4x3 = 4x3 (-8x + 4x3 + 4x5) = 0 Solving -8x + 4x3 + 4x5 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4x'. 4x(-2 + x2 + x4) = 0 Factor a trinomial. 4x((-2 + -1x2)(1 + -1x2)) = 0 Factor a difference between two squares. 4x((-2 + -1x2)((1 + x)(1 + -1x))) = 0 Ignore the factor 4.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(-2 + -1x2)' equal to zero and attempt to solve: Simplifying -2 + -1x2 = 0 Solving -2 + -1x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + -1x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -1x2 = 0 + 2 -1x2 = 0 + 2 Combine like terms: 0 + 2 = 2 -1x2 = 2 Divide each side by '-1'. x2 = -2 Simplifying x2 = -2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 3
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1Subproblem 4
Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1Solution
