Simplifying 2x2 + 18x + -264 = 0 Reorder the terms: -264 + 18x + 2x2 = 0 Solving -264 + 18x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-132 + 9x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-132 + 9x + x2)' equal to zero and attempt to solve: Simplifying -132 + 9x + x2 = 0 Solving -132 + 9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '132' to each side of the equation. -132 + 9x + 132 + x2 = 0 + 132 Reorder the terms: -132 + 132 + 9x + x2 = 0 + 132 Combine like terms: -132 + 132 = 0 0 + 9x + x2 = 0 + 132 9x + x2 = 0 + 132 Combine like terms: 0 + 132 = 132 9x + x2 = 132 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = 132 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 132 + 20.25 Combine like terms: 132 + 20.25 = 152.25 20.25 + 9x + x2 = 152.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 152.25 Calculate the square root of the right side: 12.338962679 Break this problem into two subproblems by setting (x + 4.5) equal to 12.338962679 and -12.338962679.Subproblem 1
x + 4.5 = 12.338962679 Simplifying x + 4.5 = 12.338962679 Reorder the terms: 4.5 + x = 12.338962679 Solving 4.5 + x = 12.338962679 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = 12.338962679 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 12.338962679 + -4.5 x = 12.338962679 + -4.5 Combine like terms: 12.338962679 + -4.5 = 7.838962679 x = 7.838962679 Simplifying x = 7.838962679Subproblem 2
x + 4.5 = -12.338962679 Simplifying x + 4.5 = -12.338962679 Reorder the terms: 4.5 + x = -12.338962679 Solving 4.5 + x = -12.338962679 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = -12.338962679 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -12.338962679 + -4.5 x = -12.338962679 + -4.5 Combine like terms: -12.338962679 + -4.5 = -16.838962679 x = -16.838962679 Simplifying x = -16.838962679Solution
