Simplifying x2 + 26x + -2 = 0 Reorder the terms: -2 + 26x + x2 = 0 Solving -2 + 26x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + 26x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 26x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 26x + x2 = 0 + 2 26x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 26x + x2 = 2 The x term is 26x. Take half its coefficient (13). Square it (169) and add it to both sides. Add '169' to each side of the equation. 26x + 169 + x2 = 2 + 169 Reorder the terms: 169 + 26x + x2 = 2 + 169 Combine like terms: 2 + 169 = 171 169 + 26x + x2 = 171 Factor a perfect square on the left side: (x + 13)(x + 13) = 171 Calculate the square root of the right side: 13.076696831 Break this problem into two subproblems by setting (x + 13) equal to 13.076696831 and -13.076696831.Subproblem 1
x + 13 = 13.076696831 Simplifying x + 13 = 13.076696831 Reorder the terms: 13 + x = 13.076696831 Solving 13 + x = 13.076696831 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + x = 13.076696831 + -13 Combine like terms: 13 + -13 = 0 0 + x = 13.076696831 + -13 x = 13.076696831 + -13 Combine like terms: 13.076696831 + -13 = 0.076696831 x = 0.076696831 Simplifying x = 0.076696831Subproblem 2
x + 13 = -13.076696831 Simplifying x + 13 = -13.076696831 Reorder the terms: 13 + x = -13.076696831 Solving 13 + x = -13.076696831 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + x = -13.076696831 + -13 Combine like terms: 13 + -13 = 0 0 + x = -13.076696831 + -13 x = -13.076696831 + -13 Combine like terms: -13.076696831 + -13 = -26.076696831 x = -26.076696831 Simplifying x = -26.076696831Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.076696831, -26.076696831}
