Simplifying x2 + 6x + 6x + 36 + -63 = 0 Reorder the terms: 36 + -63 + 6x + 6x + x2 = 0 Combine like terms: 36 + -63 = -27 -27 + 6x + 6x + x2 = 0 Combine like terms: 6x + 6x = 12x -27 + 12x + x2 = 0 Solving -27 + 12x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '27' to each side of the equation. -27 + 12x + 27 + x2 = 0 + 27 Reorder the terms: -27 + 27 + 12x + x2 = 0 + 27 Combine like terms: -27 + 27 = 0 0 + 12x + x2 = 0 + 27 12x + x2 = 0 + 27 Combine like terms: 0 + 27 = 27 12x + x2 = 27 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 = 27 + 36 Reorder the terms: 36 + 12x + x2 = 27 + 36 Combine like terms: 27 + 36 = 63 36 + 12x + x2 = 63 Factor a perfect square on the left side: (x + 6)(x + 6) = 63 Calculate the square root of the right side: 7.937253933 Break this problem into two subproblems by setting (x + 6) equal to 7.937253933 and -7.937253933.Subproblem 1
x + 6 = 7.937253933 Simplifying x + 6 = 7.937253933 Reorder the terms: 6 + x = 7.937253933 Solving 6 + x = 7.937253933 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 = 7.937253933 + -6 Combine like terms: 6 + -6 = 0 0 + x = 7.937253933 + -6 x = 7.937253933 + -6 Combine like terms: 7.937253933 + -6 = 1.937253933 x = 1.937253933 Simplifying x = 1.937253933Subproblem 2
x + 6 = -7.937253933 Simplifying x + 6 = -7.937253933 Reorder the terms: 6 + x = -7.937253933 Solving 6 + x = -7.937253933 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 = -7.937253933 + -6 Combine like terms: 6 + -6 = 0 0 + x = -7.937253933 + -6 x = -7.937253933 + -6 Combine like terms: -7.937253933 + -6 = -13.937253933 x = -13.937253933 Simplifying x = -13.937253933Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.937253933, -13.937253933}
