Simplifying 2x + -1(6) = 6x2 Multiply -1 * 6 2x + -6 = 6x2 Reorder the terms: -6 + 2x = 6x2 Solving -6 + 2x = 6x2 Solving for variable 'x'. Combine like terms: 6x2 + -6x2 = 0 -6 + 2x + -6x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-3 + x + -3x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-3 + x + -3x2)' equal to zero and attempt to solve: Simplifying -3 + x + -3x2 = 0 Solving -3 + x + -3x2 = 0 Begin completing the square. Divide all terms by -3 the coefficient of the squared term: Divide each side by '-3'. 1 + -0.3333333333x + x2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + -0.3333333333x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + -0.3333333333x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -0.3333333333x + x2 = 0 + -1 -0.3333333333x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 -0.3333333333x + x2 = -1 The x term is x. 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. -0.3333333333x + 0.25 + x2 = -1 + 0.25 Reorder the terms: 0.25 + -0.3333333333x + x2 = -1 + 0.25 Combine like terms: -1 + 0.25 = -0.75 0.25 + -0.3333333333x + x2 = -0.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -0.75 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.
