Simplifying x3 + 4x2 + 85x = 0 Reorder the terms: 85x + 4x2 + x3 = 0 Solving 85x + 4x2 + x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(85 + 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 '(85 + 4x + x2)' equal to zero and attempt to solve: Simplifying 85 + 4x + x2 = 0 Solving 85 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-85' to each side of the equation. 85 + 4x + -85 + x2 = 0 + -85 Reorder the terms: 85 + -85 + 4x + x2 = 0 + -85 Combine like terms: 85 + -85 = 0 0 + 4x + x2 = 0 + -85 4x + x2 = 0 + -85 Combine like terms: 0 + -85 = -85 4x + x2 = -85 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 = -85 + 4 Reorder the terms: 4 + 4x + x2 = -85 + 4 Combine like terms: -85 + 4 = -81 4 + 4x + x2 = -81 Factor a perfect square on the left side: (x + 2)(x + 2) = -81 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
