Factor out the Greatest Common Factor (GCF), '3'. 3(-3 + -2x + 3x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-3 + -2x + 3x2)' equal to zero and attempt to solve: Simplifying -3 + -2x + 3x2 = 0 Solving -3 + -2x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -1 + -0.6666666667x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -0.6666666667x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -0.6666666667x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -0.6666666667x + x2 = 0 + 1 -0.6666666667x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -0.6666666667x + x2 = 1 The x term is -0.6666666667x. Take half its coefficient (-0.3333333334). Square it (0.1111111112) and add it to both sides. Add '0.1111111112' to each side of the equation. -0.6666666667x + 0.1111111112 + x2 = 1 + 0.1111111112 Reorder the terms: 0.1111111112 + -0.6666666667x + x2 = 1 + 0.1111111112 Combine like terms: 1 + 0.1111111112 = 1.1111111112 0.1111111112 + -0.6666666667x + x2 = 1.1111111112 Factor a perfect square on the left side: (x + -0.3333333334)(x + -0.3333333334) = 1.1111111112 Calculate the square root of the right side: 1.054092553 Break this problem into two subproblems by setting (x + -0.3333333334) equal to 1.054092553 and -1.054092553.Subproblem 1
