Simplifying x(2x + 5) = 140 Reorder the terms: x(5 + 2x) = 140 (5 * x + 2x * x) = 140 (5x + 2x2) = 140 Solving 5x + 2x2 = 140 Solving for variable 'x'. Reorder the terms: -140 + 5x + 2x2 = 140 + -140 Combine like terms: 140 + -140 = 0 -140 + 5x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -70 + 2.5x + x2 = 0 Move the constant term to the right: Add '70' to each side of the equation. -70 + 2.5x + 70 + x2 = 0 + 70 Reorder the terms: -70 + 70 + 2.5x + x2 = 0 + 70 Combine like terms: -70 + 70 = 0 0 + 2.5x + x2 = 0 + 70 2.5x + x2 = 0 + 70 Combine like terms: 0 + 70 = 70 2.5x + x2 = 70 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = 70 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 70 + 1.5625 Combine like terms: 70 + 1.5625 = 71.5625 1.5625 + 2.5x + x2 = 71.5625 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 71.5625 Calculate the square root of the right side: 8.459462158 Break this problem into two subproblems by setting (x + 1.25) equal to 8.459462158 and -8.459462158.Subproblem 1
x + 1.25 = 8.459462158 Simplifying x + 1.25 = 8.459462158 Reorder the terms: 1.25 + x = 8.459462158 Solving 1.25 + x = 8.459462158 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = 8.459462158 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 8.459462158 + -1.25 x = 8.459462158 + -1.25 Combine like terms: 8.459462158 + -1.25 = 7.209462158 x = 7.209462158 Simplifying x = 7.209462158Subproblem 2
x + 1.25 = -8.459462158 Simplifying x + 1.25 = -8.459462158 Reorder the terms: 1.25 + x = -8.459462158 Solving 1.25 + x = -8.459462158 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = -8.459462158 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -8.459462158 + -1.25 x = -8.459462158 + -1.25 Combine like terms: -8.459462158 + -1.25 = -9.709462158 x = -9.709462158 Simplifying x = -9.709462158Solution
