Simplifying 9 = -9x2 + 6x Reorder the terms: 9 = 6x + -9x2 Solving 9 = 6x + -9x2 Solving for variable 'x'. Reorder the terms: 9 + -6x + 9x2 = 6x + -6x + -9x2 + 9x2 Combine like terms: 6x + -6x = 0 9 + -6x + 9x2 = 0 + -9x2 + 9x2 9 + -6x + 9x2 = -9x2 + 9x2 Combine like terms: -9x2 + 9x2 = 0 9 + -6x + 9x2 = 0 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 = -0.8888888888 0.1111111112 + -0.6666666667x + x2 = -0.8888888888 Factor a perfect square on the left side: (x + -0.3333333334)(x + -0.3333333334) = -0.8888888888 Can't calculate square root of the right side.
