Simplifying x2 + 13 = -12x Reorder the terms: 13 + x2 = -12x Solving 13 + x2 = -12x Solving for variable 'x'. Reorder the terms: 13 + 12x + x2 = -12x + 12x Combine like terms: -12x + 12x = 0 13 + 12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + 12x + -13 + x2 = 0 + -13 Reorder the terms: 13 + -13 + 12x + x2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 12x + x2 = 0 + -13 12x + x2 = 0 + -13 Combine like terms: 0 + -13 = -13 12x + x2 = -13 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 = -13 + 36 Reorder the terms: 36 + 12x + x2 = -13 + 36 Combine like terms: -13 + 36 = 23 36 + 12x + x2 = 23 Factor a perfect square on the left side: (x + 6)(x + 6) = 23 Calculate the square root of the right side: 4.795831523 Break this problem into two subproblems by setting (x + 6) equal to 4.795831523 and -4.795831523.Subproblem 1
x + 6 = 4.795831523 Simplifying x + 6 = 4.795831523 Reorder the terms: 6 + x = 4.795831523 Solving 6 + x = 4.795831523 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 = 4.795831523 + -6 Combine like terms: 6 + -6 = 0 0 + x = 4.795831523 + -6 x = 4.795831523 + -6 Combine like terms: 4.795831523 + -6 = -1.204168477 x = -1.204168477 Simplifying x = -1.204168477Subproblem 2
x + 6 = -4.795831523 Simplifying x + 6 = -4.795831523 Reorder the terms: 6 + x = -4.795831523 Solving 6 + x = -4.795831523 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 = -4.795831523 + -6 Combine like terms: 6 + -6 = 0 0 + x = -4.795831523 + -6 x = -4.795831523 + -6 Combine like terms: -4.795831523 + -6 = -10.795831523 x = -10.795831523 Simplifying x = -10.795831523Solution
