Simplifying x(2x + 7) = 250 Reorder the terms: x(7 + 2x) = 250 (7 * x + 2x * x) = 250 (7x + 2x2) = 250 Solving 7x + 2x2 = 250 Solving for variable 'x'. Reorder the terms: -250 + 7x + 2x2 = 250 + -250 Combine like terms: 250 + -250 = 0 -250 + 7x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -125 + 3.5x + x2 = 0 Move the constant term to the right: Add '125' to each side of the equation. -125 + 3.5x + 125 + x2 = 0 + 125 Reorder the terms: -125 + 125 + 3.5x + x2 = 0 + 125 Combine like terms: -125 + 125 = 0 0 + 3.5x + x2 = 0 + 125 3.5x + x2 = 0 + 125 Combine like terms: 0 + 125 = 125 3.5x + x2 = 125 The x term is 3.5x. Take half its coefficient (1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. 3.5x + 3.0625 + x2 = 125 + 3.0625 Reorder the terms: 3.0625 + 3.5x + x2 = 125 + 3.0625 Combine like terms: 125 + 3.0625 = 128.0625 3.0625 + 3.5x + x2 = 128.0625 Factor a perfect square on the left side: (x + 1.75)(x + 1.75) = 128.0625 Calculate the square root of the right side: 11.316470298 Break this problem into two subproblems by setting (x + 1.75) equal to 11.316470298 and -11.316470298.Subproblem 1
x + 1.75 = 11.316470298 Simplifying x + 1.75 = 11.316470298 Reorder the terms: 1.75 + x = 11.316470298 Solving 1.75 + x = 11.316470298 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = 11.316470298 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = 11.316470298 + -1.75 x = 11.316470298 + -1.75 Combine like terms: 11.316470298 + -1.75 = 9.566470298 x = 9.566470298 Simplifying x = 9.566470298Subproblem 2
x + 1.75 = -11.316470298 Simplifying x + 1.75 = -11.316470298 Reorder the terms: 1.75 + x = -11.316470298 Solving 1.75 + x = -11.316470298 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = -11.316470298 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = -11.316470298 + -1.75 x = -11.316470298 + -1.75 Combine like terms: -11.316470298 + -1.75 = -13.066470298 x = -13.066470298 Simplifying x = -13.066470298Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.566470298, -13.066470298}
