Simplifying 249 = 2x + x2 Solving 249 = 2x + x2 Solving for variable 'x'. Reorder the terms: 249 + -2x + -1x2 = 2x + -2x + x2 + -1x2 Combine like terms: 2x + -2x = 0 249 + -2x + -1x2 = 0 + x2 + -1x2 249 + -2x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 249 + -2x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -249 + 2x + x2 = 0 Move the constant term to the right: Add '249' to each side of the equation. -249 + 2x + 249 + x2 = 0 + 249 Reorder the terms: -249 + 249 + 2x + x2 = 0 + 249 Combine like terms: -249 + 249 = 0 0 + 2x + x2 = 0 + 249 2x + x2 = 0 + 249 Combine like terms: 0 + 249 = 249 2x + x2 = 249 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 249 + 1 Reorder the terms: 1 + 2x + x2 = 249 + 1 Combine like terms: 249 + 1 = 250 1 + 2x + x2 = 250 Factor a perfect square on the left side: (x + 1)(x + 1) = 250 Calculate the square root of the right side: 15.811388301 Break this problem into two subproblems by setting (x + 1) equal to 15.811388301 and -15.811388301.Subproblem 1
x + 1 = 15.811388301 Simplifying x + 1 = 15.811388301 Reorder the terms: 1 + x = 15.811388301 Solving 1 + x = 15.811388301 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 15.811388301 + -1 Combine like terms: 1 + -1 = 0 0 + x = 15.811388301 + -1 x = 15.811388301 + -1 Combine like terms: 15.811388301 + -1 = 14.811388301 x = 14.811388301 Simplifying x = 14.811388301Subproblem 2
x + 1 = -15.811388301 Simplifying x + 1 = -15.811388301 Reorder the terms: 1 + x = -15.811388301 Solving 1 + x = -15.811388301 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -15.811388301 + -1 Combine like terms: 1 + -1 = 0 0 + x = -15.811388301 + -1 x = -15.811388301 + -1 Combine like terms: -15.811388301 + -1 = -16.811388301 x = -16.811388301 Simplifying x = -16.811388301Solution
The solution to the problem is based on the solutions from the subproblems. x = {14.811388301, -16.811388301}
