Simplifying 2x2 + 62.8x = 1000 Reorder the terms: 62.8x + 2x2 = 1000 Solving 62.8x + 2x2 = 1000 Solving for variable 'x'. Reorder the terms: -1000 + 62.8x + 2x2 = 1000 + -1000 Combine like terms: 1000 + -1000 = 0 -1000 + 62.8x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -500 + 31.4x + x2 = 0 Move the constant term to the right: Add '500' to each side of the equation. -500 + 31.4x + 500 + x2 = 0 + 500 Reorder the terms: -500 + 500 + 31.4x + x2 = 0 + 500 Combine like terms: -500 + 500 = 0 0 + 31.4x + x2 = 0 + 500 31.4x + x2 = 0 + 500 Combine like terms: 0 + 500 = 500 31.4x + x2 = 500 The x term is 31.4x. Take half its coefficient (15.7). Square it (246.49) and add it to both sides. Add '246.49' to each side of the equation. 31.4x + 246.49 + x2 = 500 + 246.49 Reorder the terms: 246.49 + 31.4x + x2 = 500 + 246.49 Combine like terms: 500 + 246.49 = 746.49 246.49 + 31.4x + x2 = 746.49 Factor a perfect square on the left side: (x + 15.7)(x + 15.7) = 746.49 Calculate the square root of the right side: 27.321969182 Break this problem into two subproblems by setting (x + 15.7) equal to 27.321969182 and -27.321969182.Subproblem 1
x + 15.7 = 27.321969182 Simplifying x + 15.7 = 27.321969182 Reorder the terms: 15.7 + x = 27.321969182 Solving 15.7 + x = 27.321969182 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15.7' to each side of the equation. 15.7 + -15.7 + x = 27.321969182 + -15.7 Combine like terms: 15.7 + -15.7 = 0.0 0.0 + x = 27.321969182 + -15.7 x = 27.321969182 + -15.7 Combine like terms: 27.321969182 + -15.7 = 11.621969182 x = 11.621969182 Simplifying x = 11.621969182Subproblem 2
x + 15.7 = -27.321969182 Simplifying x + 15.7 = -27.321969182 Reorder the terms: 15.7 + x = -27.321969182 Solving 15.7 + x = -27.321969182 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15.7' to each side of the equation. 15.7 + -15.7 + x = -27.321969182 + -15.7 Combine like terms: 15.7 + -15.7 = 0.0 0.0 + x = -27.321969182 + -15.7 x = -27.321969182 + -15.7 Combine like terms: -27.321969182 + -15.7 = -43.021969182 x = -43.021969182 Simplifying x = -43.021969182Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.621969182, -43.021969182}
