Simplifying 6x2 + -9x + 21 = 0 Reorder the terms: 21 + -9x + 6x2 = 0 Solving 21 + -9x + 6x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3'. 3(7 + -3x + 2x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(7 + -3x + 2x2)' equal to zero and attempt to solve: Simplifying 7 + -3x + 2x2 = 0 Solving 7 + -3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 3.5 + -1.5x + x2 = 0 Move the constant term to the right: Add '-3.5' to each side of the equation. 3.5 + -1.5x + -3.5 + x2 = 0 + -3.5 Reorder the terms: 3.5 + -3.5 + -1.5x + x2 = 0 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + -1.5x + x2 = 0 + -3.5 -1.5x + x2 = 0 + -3.5 Combine like terms: 0 + -3.5 = -3.5 -1.5x + x2 = -3.5 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = -3.5 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = -3.5 + 0.5625 Combine like terms: -3.5 + 0.5625 = -2.9375 0.5625 + -1.5x + x2 = -2.9375 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = -2.9375 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.
