Simplifying x2 + 12x + -7 = 14 Reorder the terms: -7 + 12x + x2 = 14 Solving -7 + 12x + x2 = 14 Solving for variable 'x'. Reorder the terms: -7 + -14 + 12x + x2 = 14 + -14 Combine like terms: -7 + -14 = -21 -21 + 12x + x2 = 14 + -14 Combine like terms: 14 + -14 = 0 -21 + 12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '21' to each side of the equation. -21 + 12x + 21 + x2 = 0 + 21 Reorder the terms: -21 + 21 + 12x + x2 = 0 + 21 Combine like terms: -21 + 21 = 0 0 + 12x + x2 = 0 + 21 12x + x2 = 0 + 21 Combine like terms: 0 + 21 = 21 12x + x2 = 21 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 = 21 + 36 Reorder the terms: 36 + 12x + x2 = 21 + 36 Combine like terms: 21 + 36 = 57 36 + 12x + x2 = 57 Factor a perfect square on the left side: (x + 6)(x + 6) = 57 Calculate the square root of the right side: 7.549834435 Break this problem into two subproblems by setting (x + 6) equal to 7.549834435 and -7.549834435.Subproblem 1
x + 6 = 7.549834435 Simplifying x + 6 = 7.549834435 Reorder the terms: 6 + x = 7.549834435 Solving 6 + x = 7.549834435 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 = 7.549834435 + -6 Combine like terms: 6 + -6 = 0 0 + x = 7.549834435 + -6 x = 7.549834435 + -6 Combine like terms: 7.549834435 + -6 = 1.549834435 x = 1.549834435 Simplifying x = 1.549834435Subproblem 2
x + 6 = -7.549834435 Simplifying x + 6 = -7.549834435 Reorder the terms: 6 + x = -7.549834435 Solving 6 + x = -7.549834435 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 = -7.549834435 + -6 Combine like terms: 6 + -6 = 0 0 + x = -7.549834435 + -6 x = -7.549834435 + -6 Combine like terms: -7.549834435 + -6 = -13.549834435 x = -13.549834435 Simplifying x = -13.549834435Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.549834435, -13.549834435}
