Simplifying 2x(3x + -1) = 6x + -4 Reorder the terms: 2x(-1 + 3x) = 6x + -4 (-1 * 2x + 3x * 2x) = 6x + -4 (-2x + 6x2) = 6x + -4 Reorder the terms: -2x + 6x2 = -4 + 6x Solving -2x + 6x2 = -4 + 6x Solving for variable 'x'. Reorder the terms: 4 + -2x + -6x + 6x2 = -4 + 6x + 4 + -6x Combine like terms: -2x + -6x = -8x 4 + -8x + 6x2 = -4 + 6x + 4 + -6x Reorder the terms: 4 + -8x + 6x2 = -4 + 4 + 6x + -6x Combine like terms: -4 + 4 = 0 4 + -8x + 6x2 = 0 + 6x + -6x 4 + -8x + 6x2 = 6x + -6x Combine like terms: 6x + -6x = 0 4 + -8x + 6x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(2 + -4x + 3x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(2 + -4x + 3x2)' equal to zero and attempt to solve: Simplifying 2 + -4x + 3x2 = 0 Solving 2 + -4x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 0.6666666667 + -1.333333333x + x2 = 0 Move the constant term to the right: Add '-0.6666666667' to each side of the equation. 0.6666666667 + -1.333333333x + -0.6666666667 + x2 = 0 + -0.6666666667 Reorder the terms: 0.6666666667 + -0.6666666667 + -1.333333333x + x2 = 0 + -0.6666666667 Combine like terms: 0.6666666667 + -0.6666666667 = 0.0000000000 0.0000000000 + -1.333333333x + x2 = 0 + -0.6666666667 -1.333333333x + x2 = 0 + -0.6666666667 Combine like terms: 0 + -0.6666666667 = -0.6666666667 -1.333333333x + x2 = -0.6666666667 The x term is -1.333333333x. Take half its coefficient (-0.6666666665). Square it (0.4444444442) and add it to both sides. Add '0.4444444442' to each side of the equation. -1.333333333x + 0.4444444442 + x2 = -0.6666666667 + 0.4444444442 Reorder the terms: 0.4444444442 + -1.333333333x + x2 = -0.6666666667 + 0.4444444442 Combine like terms: -0.6666666667 + 0.4444444442 = -0.2222222225 0.4444444442 + -1.333333333x + x2 = -0.2222222225 Factor a perfect square on the left side: (x + -0.6666666665)(x + -0.6666666665) = -0.2222222225 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.
