Simplifying 2x2 + 27x + -180 = 0 Reorder the terms: -180 + 27x + 2x2 = 0 Solving -180 + 27x + 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'. -90 + 13.5x + x2 = 0 Move the constant term to the right: Add '90' to each side of the equation. -90 + 13.5x + 90 + x2 = 0 + 90 Reorder the terms: -90 + 90 + 13.5x + x2 = 0 + 90 Combine like terms: -90 + 90 = 0 0 + 13.5x + x2 = 0 + 90 13.5x + x2 = 0 + 90 Combine like terms: 0 + 90 = 90 13.5x + x2 = 90 The x term is 13.5x. Take half its coefficient (6.75). Square it (45.5625) and add it to both sides. Add '45.5625' to each side of the equation. 13.5x + 45.5625 + x2 = 90 + 45.5625 Reorder the terms: 45.5625 + 13.5x + x2 = 90 + 45.5625 Combine like terms: 90 + 45.5625 = 135.5625 45.5625 + 13.5x + x2 = 135.5625 Factor a perfect square on the left side: (x + 6.75)(x + 6.75) = 135.5625 Calculate the square root of the right side: 11.643131022 Break this problem into two subproblems by setting (x + 6.75) equal to 11.643131022 and -11.643131022.Subproblem 1
x + 6.75 = 11.643131022 Simplifying x + 6.75 = 11.643131022 Reorder the terms: 6.75 + x = 11.643131022 Solving 6.75 + x = 11.643131022 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.75' to each side of the equation. 6.75 + -6.75 + x = 11.643131022 + -6.75 Combine like terms: 6.75 + -6.75 = 0.00 0.00 + x = 11.643131022 + -6.75 x = 11.643131022 + -6.75 Combine like terms: 11.643131022 + -6.75 = 4.893131022 x = 4.893131022 Simplifying x = 4.893131022Subproblem 2
x + 6.75 = -11.643131022 Simplifying x + 6.75 = -11.643131022 Reorder the terms: 6.75 + x = -11.643131022 Solving 6.75 + x = -11.643131022 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.75' to each side of the equation. 6.75 + -6.75 + x = -11.643131022 + -6.75 Combine like terms: 6.75 + -6.75 = 0.00 0.00 + x = -11.643131022 + -6.75 x = -11.643131022 + -6.75 Combine like terms: -11.643131022 + -6.75 = -18.393131022 x = -18.393131022 Simplifying x = -18.393131022Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.893131022, -18.393131022}
