Simplifying -1(4x2 + 6x + 6) = 0 Reorder the terms: -1(6 + 6x + 4x2) = 0 (6 * -1 + 6x * -1 + 4x2 * -1) = 0 (-6 + -6x + -4x2) = 0 Solving -6 + -6x + -4x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-2'. -2(3 + 3x + 2x2) = 0 Ignore the factor -2.Subproblem 1
Set the factor '(3 + 3x + 2x2)' equal to zero and attempt to solve: Simplifying 3 + 3x + 2x2 = 0 Solving 3 + 3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 1.5 + 1.5x + x2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + 1.5x + -1.5 + x2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + 1.5x + x2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + 1.5x + x2 = 0 + -1.5 1.5x + x2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 1.5x + x2 = -1.5 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = -1.5 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = -1.5 + 0.5625 Combine like terms: -1.5 + 0.5625 = -0.9375 0.5625 + 1.5x + x2 = -0.9375 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = -0.9375 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.
