Simplifying 3x2 + -9x + -396 = 0 Reorder the terms: -396 + -9x + 3x2 = 0 Solving -396 + -9x + 3x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3'. 3(-132 + -3x + x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-132 + -3x + x2)' equal to zero and attempt to solve: Simplifying -132 + -3x + x2 = 0 Solving -132 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '132' to each side of the equation. -132 + -3x + 132 + x2 = 0 + 132 Reorder the terms: -132 + 132 + -3x + x2 = 0 + 132 Combine like terms: -132 + 132 = 0 0 + -3x + x2 = 0 + 132 -3x + x2 = 0 + 132 Combine like terms: 0 + 132 = 132 -3x + x2 = 132 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = 132 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 132 + 2.25 Combine like terms: 132 + 2.25 = 134.25 2.25 + -3x + x2 = 134.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 134.25 Calculate the square root of the right side: 11.586630226 Break this problem into two subproblems by setting (x + -1.5) equal to 11.586630226 and -11.586630226.Subproblem 1
x + -1.5 = 11.586630226 Simplifying x + -1.5 = 11.586630226 Reorder the terms: -1.5 + x = 11.586630226 Solving -1.5 + x = 11.586630226 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 11.586630226 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 11.586630226 + 1.5 x = 11.586630226 + 1.5 Combine like terms: 11.586630226 + 1.5 = 13.086630226 x = 13.086630226 Simplifying x = 13.086630226Subproblem 2
x + -1.5 = -11.586630226 Simplifying x + -1.5 = -11.586630226 Reorder the terms: -1.5 + x = -11.586630226 Solving -1.5 + x = -11.586630226 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -11.586630226 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -11.586630226 + 1.5 x = -11.586630226 + 1.5 Combine like terms: -11.586630226 + 1.5 = -10.086630226 x = -10.086630226 Simplifying x = -10.086630226Solution
