Simplifying 18x3 + -15x2 + 9x = 0 Reorder the terms: 9x + -15x2 + 18x3 = 0 Solving 9x + -15x2 + 18x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3x'. 3x(3 + -5x + 6x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(3 + -5x + 6x2)' equal to zero and attempt to solve: Simplifying 3 + -5x + 6x2 = 0 Solving 3 + -5x + 6x2 = 0 Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. 0.5 + -0.8333333333x + x2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -0.8333333333x + -0.5 + x2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -0.8333333333x + x2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -0.8333333333x + x2 = 0 + -0.5 -0.8333333333x + x2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -0.8333333333x + x2 = -0.5 The x term is -0.8333333333x. Take half its coefficient (-0.4166666667). Square it (0.1736111111) and add it to both sides. Add '0.1736111111' to each side of the equation. -0.8333333333x + 0.1736111111 + x2 = -0.5 + 0.1736111111 Reorder the terms: 0.1736111111 + -0.8333333333x + x2 = -0.5 + 0.1736111111 Combine like terms: -0.5 + 0.1736111111 = -0.3263888889 0.1736111111 + -0.8333333333x + x2 = -0.3263888889 Factor a perfect square on the left side: (x + -0.4166666667)(x + -0.4166666667) = -0.3263888889 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.Solution
