Simplifying -8x2 + -7x = 3 Reorder the terms: -7x + -8x2 = 3 Solving -7x + -8x2 = 3 Solving for variable 'x'. Reorder the terms: -3 + -7x + -8x2 = 3 + -3 Combine like terms: 3 + -3 = 0 -3 + -7x + -8x2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(3 + 7x + 8x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(3 + 7x + 8x2)' equal to zero and attempt to solve: Simplifying 3 + 7x + 8x2 = 0 Solving 3 + 7x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.375 + 0.875x + x2 = 0 Move the constant term to the right: Add '-0.375' to each side of the equation. 0.375 + 0.875x + -0.375 + x2 = 0 + -0.375 Reorder the terms: 0.375 + -0.375 + 0.875x + x2 = 0 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + 0.875x + x2 = 0 + -0.375 0.875x + x2 = 0 + -0.375 Combine like terms: 0 + -0.375 = -0.375 0.875x + x2 = -0.375 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 = -0.375 + 0.19140625 Reorder the terms: 0.19140625 + 0.875x + x2 = -0.375 + 0.19140625 Combine like terms: -0.375 + 0.19140625 = -0.18359375 0.19140625 + 0.875x + x2 = -0.18359375 Factor a perfect square on the left side: (x + 0.4375)(x + 0.4375) = -0.18359375 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. The solution to this equation could not be determined.
