Simplifying x2 + 24x + -300 = 0 Reorder the terms: -300 + 24x + x2 = 0 Solving -300 + 24x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '300' to each side of the equation. -300 + 24x + 300 + x2 = 0 + 300 Reorder the terms: -300 + 300 + 24x + x2 = 0 + 300 Combine like terms: -300 + 300 = 0 0 + 24x + x2 = 0 + 300 24x + x2 = 0 + 300 Combine like terms: 0 + 300 = 300 24x + x2 = 300 The x term is 24x. Take half its coefficient (12). Square it (144) and add it to both sides. Add '144' to each side of the equation. 24x + 144 + x2 = 300 + 144 Reorder the terms: 144 + 24x + x2 = 300 + 144 Combine like terms: 300 + 144 = 444 144 + 24x + x2 = 444 Factor a perfect square on the left side: (x + 12)(x + 12) = 444 Calculate the square root of the right side: 21.071307506 Break this problem into two subproblems by setting (x + 12) equal to 21.071307506 and -21.071307506.Subproblem 1
x + 12 = 21.071307506 Simplifying x + 12 = 21.071307506 Reorder the terms: 12 + x = 21.071307506 Solving 12 + x = 21.071307506 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + x = 21.071307506 + -12 Combine like terms: 12 + -12 = 0 0 + x = 21.071307506 + -12 x = 21.071307506 + -12 Combine like terms: 21.071307506 + -12 = 9.071307506 x = 9.071307506 Simplifying x = 9.071307506Subproblem 2
x + 12 = -21.071307506 Simplifying x + 12 = -21.071307506 Reorder the terms: 12 + x = -21.071307506 Solving 12 + x = -21.071307506 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + x = -21.071307506 + -12 Combine like terms: 12 + -12 = 0 0 + x = -21.071307506 + -12 x = -21.071307506 + -12 Combine like terms: -21.071307506 + -12 = -33.071307506 x = -33.071307506 Simplifying x = -33.071307506Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.071307506, -33.071307506}
