Simplifying 8x3 + -7x2 + 2x = 0 Reorder the terms: 2x + -7x2 + 8x3 = 0 Solving 2x + -7x2 + 8x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(2 + -7x + 8x2) = 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 '(2 + -7x + 8x2)' equal to zero and attempt to solve: Simplifying 2 + -7x + 8x2 = 0 Solving 2 + -7x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.25 + -0.875x + x2 = 0 Move the constant term to the right: Add '-0.25' to each side of the equation. 0.25 + -0.875x + -0.25 + x2 = 0 + -0.25 Reorder the terms: 0.25 + -0.25 + -0.875x + x2 = 0 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + -0.875x + x2 = 0 + -0.25 -0.875x + x2 = 0 + -0.25 Combine like terms: 0 + -0.25 = -0.25 -0.875x + x2 = -0.25 The x term is -0.875x. Take half its coefficient (-0.4375). Square it (0.19140625) and add it to both sides. Add '0.19140625' to each side of the equation. -0.875x + 0.19140625 + x2 = -0.25 + 0.19140625 Reorder the terms: 0.19140625 + -0.875x + x2 = -0.25 + 0.19140625 Combine like terms: -0.25 + 0.19140625 = -0.05859375 0.19140625 + -0.875x + x2 = -0.05859375 Factor a perfect square on the left side: (x + -0.4375)(x + -0.4375) = -0.05859375 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
