Simplifying -1(8x2 + -6x + 6) = 0 Reorder the terms: -1(6 + -6x + 8x2) = 0 (6 * -1 + -6x * -1 + 8x2 * -1) = 0 (-6 + 6x + -8x2) = 0 Solving -6 + 6x + -8x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-3 + 3x + -4x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-3 + 3x + -4x2)' equal to zero and attempt to solve: Simplifying -3 + 3x + -4x2 = 0 Solving -3 + 3x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 0.75 + -0.75x + x2 = 0 Move the constant term to the right: Add '-0.75' to each side of the equation. 0.75 + -0.75x + -0.75 + x2 = 0 + -0.75 Reorder the terms: 0.75 + -0.75 + -0.75x + x2 = 0 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + -0.75x + x2 = 0 + -0.75 -0.75x + x2 = 0 + -0.75 Combine like terms: 0 + -0.75 = -0.75 -0.75x + x2 = -0.75 The x term is -0.75x. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75x + 0.140625 + x2 = -0.75 + 0.140625 Reorder the terms: 0.140625 + -0.75x + x2 = -0.75 + 0.140625 Combine like terms: -0.75 + 0.140625 = -0.609375 0.140625 + -0.75x + x2 = -0.609375 Factor a perfect square on the left side: (x + -0.375)(x + -0.375) = -0.609375 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.
