Simplifying x2 + 12x + -2 = 2 Reorder the terms: -2 + 12x + x2 = 2 Solving -2 + 12x + x2 = 2 Solving for variable 'x'. Reorder the terms: -2 + -2 + 12x + x2 = 2 + -2 Combine like terms: -2 + -2 = -4 -4 + 12x + x2 = 2 + -2 Combine like terms: 2 + -2 = 0 -4 + 12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '4' to each side of the equation. -4 + 12x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + 12x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 12x + x2 = 0 + 4 12x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 12x + x2 = 4 The x term is 12x. Take half its coefficient (6). Square it (36) and add it to both sides. Add '36' to each side of the equation. 12x + 36 + x2 = 4 + 36 Reorder the terms: 36 + 12x + x2 = 4 + 36 Combine like terms: 4 + 36 = 40 36 + 12x + x2 = 40 Factor a perfect square on the left side: (x + 6)(x + 6) = 40 Calculate the square root of the right side: 6.32455532 Break this problem into two subproblems by setting (x + 6) equal to 6.32455532 and -6.32455532.Subproblem 1
x + 6 = 6.32455532 Simplifying x + 6 = 6.32455532 Reorder the terms: 6 + x = 6.32455532 Solving 6 + x = 6.32455532 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = 6.32455532 + -6 Combine like terms: 6 + -6 = 0 0 + x = 6.32455532 + -6 x = 6.32455532 + -6 Combine like terms: 6.32455532 + -6 = 0.32455532 x = 0.32455532 Simplifying x = 0.32455532Subproblem 2
x + 6 = -6.32455532 Simplifying x + 6 = -6.32455532 Reorder the terms: 6 + x = -6.32455532 Solving 6 + x = -6.32455532 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x = -6.32455532 + -6 Combine like terms: 6 + -6 = 0 0 + x = -6.32455532 + -6 x = -6.32455532 + -6 Combine like terms: -6.32455532 + -6 = -12.32455532 x = -12.32455532 Simplifying x = -12.32455532Solution
