Simplifying x2 + 2x + -141 = 0 Reorder the terms: -141 + 2x + x2 = 0 Solving -141 + 2x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '141' to each side of the equation. -141 + 2x + 141 + x2 = 0 + 141 Reorder the terms: -141 + 141 + 2x + x2 = 0 + 141 Combine like terms: -141 + 141 = 0 0 + 2x + x2 = 0 + 141 2x + x2 = 0 + 141 Combine like terms: 0 + 141 = 141 2x + x2 = 141 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 = 141 + 1 Reorder the terms: 1 + 2x + x2 = 141 + 1 Combine like terms: 141 + 1 = 142 1 + 2x + x2 = 142 Factor a perfect square on the left side: (x + 1)(x + 1) = 142 Calculate the square root of the right side: 11.916375288 Break this problem into two subproblems by setting (x + 1) equal to 11.916375288 and -11.916375288.Subproblem 1
x + 1 = 11.916375288 Simplifying x + 1 = 11.916375288 Reorder the terms: 1 + x = 11.916375288 Solving 1 + x = 11.916375288 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 = 11.916375288 + -1 Combine like terms: 1 + -1 = 0 0 + x = 11.916375288 + -1 x = 11.916375288 + -1 Combine like terms: 11.916375288 + -1 = 10.916375288 x = 10.916375288 Simplifying x = 10.916375288Subproblem 2
x + 1 = -11.916375288 Simplifying x + 1 = -11.916375288 Reorder the terms: 1 + x = -11.916375288 Solving 1 + x = -11.916375288 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 = -11.916375288 + -1 Combine like terms: 1 + -1 = 0 0 + x = -11.916375288 + -1 x = -11.916375288 + -1 Combine like terms: -11.916375288 + -1 = -12.916375288 x = -12.916375288 Simplifying x = -12.916375288Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.916375288, -12.916375288}
