Simplifying x2 + 12x = 100 Reorder the terms: 12x + x2 = 100 Solving 12x + x2 = 100 Solving for variable 'x'. Reorder the terms: -100 + 12x + x2 = 100 + -100 Combine like terms: 100 + -100 = 0 -100 + 12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '100' to each side of the equation. -100 + 12x + 100 + x2 = 0 + 100 Reorder the terms: -100 + 100 + 12x + x2 = 0 + 100 Combine like terms: -100 + 100 = 0 0 + 12x + x2 = 0 + 100 12x + x2 = 0 + 100 Combine like terms: 0 + 100 = 100 12x + x2 = 100 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 = 100 + 36 Reorder the terms: 36 + 12x + x2 = 100 + 36 Combine like terms: 100 + 36 = 136 36 + 12x + x2 = 136 Factor a perfect square on the left side: (x + 6)(x + 6) = 136 Calculate the square root of the right side: 11.66190379 Break this problem into two subproblems by setting (x + 6) equal to 11.66190379 and -11.66190379.Subproblem 1
x + 6 = 11.66190379 Simplifying x + 6 = 11.66190379 Reorder the terms: 6 + x = 11.66190379 Solving 6 + x = 11.66190379 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 = 11.66190379 + -6 Combine like terms: 6 + -6 = 0 0 + x = 11.66190379 + -6 x = 11.66190379 + -6 Combine like terms: 11.66190379 + -6 = 5.66190379 x = 5.66190379 Simplifying x = 5.66190379Subproblem 2
x + 6 = -11.66190379 Simplifying x + 6 = -11.66190379 Reorder the terms: 6 + x = -11.66190379 Solving 6 + x = -11.66190379 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 = -11.66190379 + -6 Combine like terms: 6 + -6 = 0 0 + x = -11.66190379 + -6 x = -11.66190379 + -6 Combine like terms: -11.66190379 + -6 = -17.66190379 x = -17.66190379 Simplifying x = -17.66190379Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.66190379, -17.66190379}
