Simplifying 6x2 + -66x + 12 = 0 Reorder the terms: 12 + -66x + 6x2 = 0 Solving 12 + -66x + 6x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '6'. 6(2 + -11x + x2) = 0 Ignore the factor 6.Subproblem 1
Set the factor '(2 + -11x + x2)' equal to zero and attempt to solve: Simplifying 2 + -11x + x2 = 0 Solving 2 + -11x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + -11x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + -11x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -11x + x2 = 0 + -2 -11x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -11x + x2 = -2 The x term is -11x. Take half its coefficient (-5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. -11x + 30.25 + x2 = -2 + 30.25 Reorder the terms: 30.25 + -11x + x2 = -2 + 30.25 Combine like terms: -2 + 30.25 = 28.25 30.25 + -11x + x2 = 28.25 Factor a perfect square on the left side: (x + -5.5)(x + -5.5) = 28.25 Calculate the square root of the right side: 5.315072906 Break this problem into two subproblems by setting (x + -5.5) equal to 5.315072906 and -5.315072906.Subproblem 1
x + -5.5 = 5.315072906 Simplifying x + -5.5 = 5.315072906 Reorder the terms: -5.5 + x = 5.315072906 Solving -5.5 + x = 5.315072906 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + x = 5.315072906 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + x = 5.315072906 + 5.5 x = 5.315072906 + 5.5 Combine like terms: 5.315072906 + 5.5 = 10.815072906 x = 10.815072906 Simplifying x = 10.815072906Subproblem 2
x + -5.5 = -5.315072906 Simplifying x + -5.5 = -5.315072906 Reorder the terms: -5.5 + x = -5.315072906 Solving -5.5 + x = -5.315072906 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + x = -5.315072906 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + x = -5.315072906 + 5.5 x = -5.315072906 + 5.5 Combine like terms: -5.315072906 + 5.5 = 0.184927094 x = 0.184927094 Simplifying x = 0.184927094Solution
