Simplifying 0 = x2 + 2x + -167 Reorder the terms: 0 = -167 + 2x + x2 Solving 0 = -167 + 2x + x2 Solving for variable 'x'. Combine like terms: 0 + 167 = 167 167 + -2x + -1x2 = -167 + 2x + x2 + 167 + -2x + -1x2 Reorder the terms: 167 + -2x + -1x2 = -167 + 167 + 2x + -2x + x2 + -1x2 Combine like terms: -167 + 167 = 0 167 + -2x + -1x2 = 0 + 2x + -2x + x2 + -1x2 167 + -2x + -1x2 = 2x + -2x + x2 + -1x2 Combine like terms: 2x + -2x = 0 167 + -2x + -1x2 = 0 + x2 + -1x2 167 + -2x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 167 + -2x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -167 + 2x + x2 = 0 Move the constant term to the right: Add '167' to each side of the equation. -167 + 2x + 167 + x2 = 0 + 167 Reorder the terms: -167 + 167 + 2x + x2 = 0 + 167 Combine like terms: -167 + 167 = 0 0 + 2x + x2 = 0 + 167 2x + x2 = 0 + 167 Combine like terms: 0 + 167 = 167 2x + x2 = 167 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 = 167 + 1 Reorder the terms: 1 + 2x + x2 = 167 + 1 Combine like terms: 167 + 1 = 168 1 + 2x + x2 = 168 Factor a perfect square on the left side: (x + 1)(x + 1) = 168 Calculate the square root of the right side: 12.961481397 Break this problem into two subproblems by setting (x + 1) equal to 12.961481397 and -12.961481397.Subproblem 1
x + 1 = 12.961481397 Simplifying x + 1 = 12.961481397 Reorder the terms: 1 + x = 12.961481397 Solving 1 + x = 12.961481397 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 = 12.961481397 + -1 Combine like terms: 1 + -1 = 0 0 + x = 12.961481397 + -1 x = 12.961481397 + -1 Combine like terms: 12.961481397 + -1 = 11.961481397 x = 11.961481397 Simplifying x = 11.961481397Subproblem 2
x + 1 = -12.961481397 Simplifying x + 1 = -12.961481397 Reorder the terms: 1 + x = -12.961481397 Solving 1 + x = -12.961481397 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 = -12.961481397 + -1 Combine like terms: 1 + -1 = 0 0 + x = -12.961481397 + -1 x = -12.961481397 + -1 Combine like terms: -12.961481397 + -1 = -13.961481397 x = -13.961481397 Simplifying x = -13.961481397Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.961481397, -13.961481397}
