Simplifying 2x2 + 15x + -180 = 0 Reorder the terms: -180 + 15x + 2x2 = 0 Solving -180 + 15x + 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 + 7.5x + x2 = 0 Move the constant term to the right: Add '90' to each side of the equation. -90 + 7.5x + 90 + x2 = 0 + 90 Reorder the terms: -90 + 90 + 7.5x + x2 = 0 + 90 Combine like terms: -90 + 90 = 0 0 + 7.5x + x2 = 0 + 90 7.5x + x2 = 0 + 90 Combine like terms: 0 + 90 = 90 7.5x + x2 = 90 The x term is 7.5x. Take half its coefficient (3.75). Square it (14.0625) and add it to both sides. Add '14.0625' to each side of the equation. 7.5x + 14.0625 + x2 = 90 + 14.0625 Reorder the terms: 14.0625 + 7.5x + x2 = 90 + 14.0625 Combine like terms: 90 + 14.0625 = 104.0625 14.0625 + 7.5x + x2 = 104.0625 Factor a perfect square on the left side: (x + 3.75)(x + 3.75) = 104.0625 Calculate the square root of the right side: 10.201102882 Break this problem into two subproblems by setting (x + 3.75) equal to 10.201102882 and -10.201102882.Subproblem 1
x + 3.75 = 10.201102882 Simplifying x + 3.75 = 10.201102882 Reorder the terms: 3.75 + x = 10.201102882 Solving 3.75 + x = 10.201102882 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.75' to each side of the equation. 3.75 + -3.75 + x = 10.201102882 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + x = 10.201102882 + -3.75 x = 10.201102882 + -3.75 Combine like terms: 10.201102882 + -3.75 = 6.451102882 x = 6.451102882 Simplifying x = 6.451102882Subproblem 2
x + 3.75 = -10.201102882 Simplifying x + 3.75 = -10.201102882 Reorder the terms: 3.75 + x = -10.201102882 Solving 3.75 + x = -10.201102882 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.75' to each side of the equation. 3.75 + -3.75 + x = -10.201102882 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + x = -10.201102882 + -3.75 x = -10.201102882 + -3.75 Combine like terms: -10.201102882 + -3.75 = -13.951102882 x = -13.951102882 Simplifying x = -13.951102882Solution
