Simplifying (x3 + -4x2 + 7x + -2)(2x) = 0 Reorder the terms: (-2 + 7x + -4x2 + x3)(2x) = 0 Remove parenthesis around (2x) (-2 + 7x + -4x2 + x3) * 2x = 0 Reorder the terms for easier multiplication: 2x(-2 + 7x + -4x2 + x3) = 0 (-2 * 2x + 7x * 2x + -4x2 * 2x + x3 * 2x) = 0 (-4x + 14x2 + -8x3 + 2x4) = 0 Solving -4x + 14x2 + -8x3 + 2x4 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2x'. 2x(-2 + 7x + -4x2 + x3) = 0 Ignore the factor 2.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 + 7x + -4x2 + x3)' equal to zero and attempt to solve: Simplifying -2 + 7x + -4x2 + x3 = 0 Solving -2 + 7x + -4x2 + x3 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
