Simplifying x3 + -4x2 + 16x = 0 Reorder the terms: 16x + -4x2 + x3 = 0 Solving 16x + -4x2 + x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(16 + -4x + x2) = 0Subproblem 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 '(16 + -4x + x2)' equal to zero and attempt to solve: Simplifying 16 + -4x + x2 = 0 Solving 16 + -4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + -4x + -16 + x2 = 0 + -16 Reorder the terms: 16 + -16 + -4x + x2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -4x + x2 = 0 + -16 -4x + x2 = 0 + -16 Combine like terms: 0 + -16 = -16 -4x + x2 = -16 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = -16 + 4 Reorder the terms: 4 + -4x + x2 = -16 + 4 Combine like terms: -16 + 4 = -12 4 + -4x + x2 = -12 Factor a perfect square on the left side: (x + -2)(x + -2) = -12 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
