Simplifying 0 = 8x2 + -8x + 6 Reorder the terms: 0 = 6 + -8x + 8x2 Solving 0 = 6 + -8x + 8x2 Solving for variable 'x'. Combine like terms: 0 + -6 = -6 -6 + 8x + -8x2 = 6 + -8x + 8x2 + -6 + 8x + -8x2 Reorder the terms: -6 + 8x + -8x2 = 6 + -6 + -8x + 8x + 8x2 + -8x2 Combine like terms: 6 + -6 = 0 -6 + 8x + -8x2 = 0 + -8x + 8x + 8x2 + -8x2 -6 + 8x + -8x2 = -8x + 8x + 8x2 + -8x2 Combine like terms: -8x + 8x = 0 -6 + 8x + -8x2 = 0 + 8x2 + -8x2 -6 + 8x + -8x2 = 8x2 + -8x2 Combine like terms: 8x2 + -8x2 = 0 -6 + 8x + -8x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-3 + 4x + -4x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-3 + 4x + -4x2)' equal to zero and attempt to solve: Simplifying -3 + 4x + -4x2 = 0 Solving -3 + 4x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 0.75 + -1x + x2 = 0 Move the constant term to the right: Add '-0.75' to each side of the equation. 0.75 + -1x + -0.75 + x2 = 0 + -0.75 Reorder the terms: 0.75 + -0.75 + -1x + x2 = 0 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + -1x + x2 = 0 + -0.75 -1x + x2 = 0 + -0.75 Combine like terms: 0 + -0.75 = -0.75 -1x + x2 = -0.75 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = -0.75 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -0.75 + 0.25 Combine like terms: -0.75 + 0.25 = -0.5 0.25 + -1x + x2 = -0.5 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -0.5 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.
