Simplifying 2x2 + -11x + -18 = 0 Reorder the terms: -18 + -11x + 2x2 = 0 Solving -18 + -11x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -9 + -5.5x + x2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + -5.5x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + -5.5x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -5.5x + x2 = 0 + 9 -5.5x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 -5.5x + x2 = 9 The x term is -5.5x. Take half its coefficient (-2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. -5.5x + 7.5625 + x2 = 9 + 7.5625 Reorder the terms: 7.5625 + -5.5x + x2 = 9 + 7.5625 Combine like terms: 9 + 7.5625 = 16.5625 7.5625 + -5.5x + x2 = 16.5625 Factor a perfect square on the left side: (x + -2.75)(x + -2.75) = 16.5625 Calculate the square root of the right side: 4.069705149 Break this problem into two subproblems by setting (x + -2.75) equal to 4.069705149 and -4.069705149.Subproblem 1
x + -2.75 = 4.069705149 Simplifying x + -2.75 = 4.069705149 Reorder the terms: -2.75 + x = 4.069705149 Solving -2.75 + x = 4.069705149 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + x = 4.069705149 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + x = 4.069705149 + 2.75 x = 4.069705149 + 2.75 Combine like terms: 4.069705149 + 2.75 = 6.819705149 x = 6.819705149 Simplifying x = 6.819705149Subproblem 2
x + -2.75 = -4.069705149 Simplifying x + -2.75 = -4.069705149 Reorder the terms: -2.75 + x = -4.069705149 Solving -2.75 + x = -4.069705149 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + x = -4.069705149 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + x = -4.069705149 + 2.75 x = -4.069705149 + 2.75 Combine like terms: -4.069705149 + 2.75 = -1.319705149 x = -1.319705149 Simplifying x = -1.319705149Solution
