Simplifying 2x2 + 3x = 220 Reorder the terms: 3x + 2x2 = 220 Solving 3x + 2x2 = 220 Solving for variable 'x'. Reorder the terms: -220 + 3x + 2x2 = 220 + -220 Combine like terms: 220 + -220 = 0 -220 + 3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -110 + 1.5x + x2 = 0 Move the constant term to the right: Add '110' to each side of the equation. -110 + 1.5x + 110 + x2 = 0 + 110 Reorder the terms: -110 + 110 + 1.5x + x2 = 0 + 110 Combine like terms: -110 + 110 = 0 0 + 1.5x + x2 = 0 + 110 1.5x + x2 = 0 + 110 Combine like terms: 0 + 110 = 110 1.5x + x2 = 110 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = 110 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 110 + 0.5625 Combine like terms: 110 + 0.5625 = 110.5625 0.5625 + 1.5x + x2 = 110.5625 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 110.5625 Calculate the square root of the right side: 10.514870422 Break this problem into two subproblems by setting (x + 0.75) equal to 10.514870422 and -10.514870422.Subproblem 1
x + 0.75 = 10.514870422 Simplifying x + 0.75 = 10.514870422 Reorder the terms: 0.75 + x = 10.514870422 Solving 0.75 + x = 10.514870422 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = 10.514870422 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 10.514870422 + -0.75 x = 10.514870422 + -0.75 Combine like terms: 10.514870422 + -0.75 = 9.764870422 x = 9.764870422 Simplifying x = 9.764870422Subproblem 2
x + 0.75 = -10.514870422 Simplifying x + 0.75 = -10.514870422 Reorder the terms: 0.75 + x = -10.514870422 Solving 0.75 + x = -10.514870422 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = -10.514870422 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -10.514870422 + -0.75 x = -10.514870422 + -0.75 Combine like terms: -10.514870422 + -0.75 = -11.264870422 x = -11.264870422 Simplifying x = -11.264870422Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.764870422, -11.264870422}
