Simplifying 12x2 + -12x + 39 = 0 Reorder the terms: 39 + -12x + 12x2 = 0 Solving 39 + -12x + 12x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3'. 3(13 + -4x + 4x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(13 + -4x + 4x2)' equal to zero and attempt to solve: Simplifying 13 + -4x + 4x2 = 0 Solving 13 + -4x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 3.25 + -1x + x2 = 0 Move the constant term to the right: Add '-3.25' to each side of the equation. 3.25 + -1x + -3.25 + x2 = 0 + -3.25 Reorder the terms: 3.25 + -3.25 + -1x + x2 = 0 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + -1x + x2 = 0 + -3.25 -1x + x2 = 0 + -3.25 Combine like terms: 0 + -3.25 = -3.25 -1x + x2 = -3.25 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 = -3.25 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -3.25 + 0.25 Combine like terms: -3.25 + 0.25 = -3 0.25 + -1x + x2 = -3 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -3 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.
