Simplifying 2x2 + 5x = 173 Reorder the terms: 5x + 2x2 = 173 Solving 5x + 2x2 = 173 Solving for variable 'x'. Reorder the terms: -173 + 5x + 2x2 = 173 + -173 Combine like terms: 173 + -173 = 0 -173 + 5x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -86.5 + 2.5x + x2 = 0 Move the constant term to the right: Add '86.5' to each side of the equation. -86.5 + 2.5x + 86.5 + x2 = 0 + 86.5 Reorder the terms: -86.5 + 86.5 + 2.5x + x2 = 0 + 86.5 Combine like terms: -86.5 + 86.5 = 0.0 0.0 + 2.5x + x2 = 0 + 86.5 2.5x + x2 = 0 + 86.5 Combine like terms: 0 + 86.5 = 86.5 2.5x + x2 = 86.5 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 = 86.5 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 86.5 + 1.5625 Combine like terms: 86.5 + 1.5625 = 88.0625 1.5625 + 2.5x + x2 = 88.0625 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 88.0625 Calculate the square root of the right side: 9.38416219 Break this problem into two subproblems by setting (x + 1.25) equal to 9.38416219 and -9.38416219.Subproblem 1
x + 1.25 = 9.38416219 Simplifying x + 1.25 = 9.38416219 Reorder the terms: 1.25 + x = 9.38416219 Solving 1.25 + x = 9.38416219 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 = 9.38416219 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 9.38416219 + -1.25 x = 9.38416219 + -1.25 Combine like terms: 9.38416219 + -1.25 = 8.13416219 x = 8.13416219 Simplifying x = 8.13416219Subproblem 2
x + 1.25 = -9.38416219 Simplifying x + 1.25 = -9.38416219 Reorder the terms: 1.25 + x = -9.38416219 Solving 1.25 + x = -9.38416219 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 = -9.38416219 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -9.38416219 + -1.25 x = -9.38416219 + -1.25 Combine like terms: -9.38416219 + -1.25 = -10.63416219 x = -10.63416219 Simplifying x = -10.63416219Solution
The solution to the problem is based on the solutions from the subproblems. x = {8.13416219, -10.63416219}
