Simplifying 2x2 + 17x + -45 = 0 Reorder the terms: -45 + 17x + 2x2 = 0 Solving -45 + 17x + 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'. -22.5 + 8.5x + x2 = 0 Move the constant term to the right: Add '22.5' to each side of the equation. -22.5 + 8.5x + 22.5 + x2 = 0 + 22.5 Reorder the terms: -22.5 + 22.5 + 8.5x + x2 = 0 + 22.5 Combine like terms: -22.5 + 22.5 = 0.0 0.0 + 8.5x + x2 = 0 + 22.5 8.5x + x2 = 0 + 22.5 Combine like terms: 0 + 22.5 = 22.5 8.5x + x2 = 22.5 The x term is 8.5x. Take half its coefficient (4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. 8.5x + 18.0625 + x2 = 22.5 + 18.0625 Reorder the terms: 18.0625 + 8.5x + x2 = 22.5 + 18.0625 Combine like terms: 22.5 + 18.0625 = 40.5625 18.0625 + 8.5x + x2 = 40.5625 Factor a perfect square on the left side: (x + 4.25)(x + 4.25) = 40.5625 Calculate the square root of the right side: 6.368869601 Break this problem into two subproblems by setting (x + 4.25) equal to 6.368869601 and -6.368869601.Subproblem 1
x + 4.25 = 6.368869601 Simplifying x + 4.25 = 6.368869601 Reorder the terms: 4.25 + x = 6.368869601 Solving 4.25 + x = 6.368869601 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + x = 6.368869601 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = 6.368869601 + -4.25 x = 6.368869601 + -4.25 Combine like terms: 6.368869601 + -4.25 = 2.118869601 x = 2.118869601 Simplifying x = 2.118869601Subproblem 2
x + 4.25 = -6.368869601 Simplifying x + 4.25 = -6.368869601 Reorder the terms: 4.25 + x = -6.368869601 Solving 4.25 + x = -6.368869601 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + x = -6.368869601 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = -6.368869601 + -4.25 x = -6.368869601 + -4.25 Combine like terms: -6.368869601 + -4.25 = -10.618869601 x = -10.618869601 Simplifying x = -10.618869601Solution
