Simplifying 2x2 + 35x + 120 = 0 Reorder the terms: 120 + 35x + 2x2 = 0 Solving 120 + 35x + 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'. 60 + 17.5x + x2 = 0 Move the constant term to the right: Add '-60' to each side of the equation. 60 + 17.5x + -60 + x2 = 0 + -60 Reorder the terms: 60 + -60 + 17.5x + x2 = 0 + -60 Combine like terms: 60 + -60 = 0 0 + 17.5x + x2 = 0 + -60 17.5x + x2 = 0 + -60 Combine like terms: 0 + -60 = -60 17.5x + x2 = -60 The x term is 17.5x. Take half its coefficient (8.75). Square it (76.5625) and add it to both sides. Add '76.5625' to each side of the equation. 17.5x + 76.5625 + x2 = -60 + 76.5625 Reorder the terms: 76.5625 + 17.5x + x2 = -60 + 76.5625 Combine like terms: -60 + 76.5625 = 16.5625 76.5625 + 17.5x + x2 = 16.5625 Factor a perfect square on the left side: (x + 8.75)(x + 8.75) = 16.5625 Calculate the square root of the right side: 4.069705149 Break this problem into two subproblems by setting (x + 8.75) equal to 4.069705149 and -4.069705149.Subproblem 1
x + 8.75 = 4.069705149 Simplifying x + 8.75 = 4.069705149 Reorder the terms: 8.75 + x = 4.069705149 Solving 8.75 + x = 4.069705149 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8.75' to each side of the equation. 8.75 + -8.75 + x = 4.069705149 + -8.75 Combine like terms: 8.75 + -8.75 = 0.00 0.00 + x = 4.069705149 + -8.75 x = 4.069705149 + -8.75 Combine like terms: 4.069705149 + -8.75 = -4.680294851 x = -4.680294851 Simplifying x = -4.680294851Subproblem 2
x + 8.75 = -4.069705149 Simplifying x + 8.75 = -4.069705149 Reorder the terms: 8.75 + x = -4.069705149 Solving 8.75 + x = -4.069705149 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8.75' to each side of the equation. 8.75 + -8.75 + x = -4.069705149 + -8.75 Combine like terms: 8.75 + -8.75 = 0.00 0.00 + x = -4.069705149 + -8.75 x = -4.069705149 + -8.75 Combine like terms: -4.069705149 + -8.75 = -12.819705149 x = -12.819705149 Simplifying x = -12.819705149Solution
