Simplifying x2 + 15x + 38 = 0 Reorder the terms: 38 + 15x + x2 = 0 Solving 38 + 15x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-38' to each side of the equation. 38 + 15x + -38 + x2 = 0 + -38 Reorder the terms: 38 + -38 + 15x + x2 = 0 + -38 Combine like terms: 38 + -38 = 0 0 + 15x + x2 = 0 + -38 15x + x2 = 0 + -38 Combine like terms: 0 + -38 = -38 15x + x2 = -38 The x term is 15x. Take half its coefficient (7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. 15x + 56.25 + x2 = -38 + 56.25 Reorder the terms: 56.25 + 15x + x2 = -38 + 56.25 Combine like terms: -38 + 56.25 = 18.25 56.25 + 15x + x2 = 18.25 Factor a perfect square on the left side: (x + 7.5)(x + 7.5) = 18.25 Calculate the square root of the right side: 4.272001873 Break this problem into two subproblems by setting (x + 7.5) equal to 4.272001873 and -4.272001873.Subproblem 1
x + 7.5 = 4.272001873 Simplifying x + 7.5 = 4.272001873 Reorder the terms: 7.5 + x = 4.272001873 Solving 7.5 + x = 4.272001873 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + x = 4.272001873 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = 4.272001873 + -7.5 x = 4.272001873 + -7.5 Combine like terms: 4.272001873 + -7.5 = -3.227998127 x = -3.227998127 Simplifying x = -3.227998127Subproblem 2
x + 7.5 = -4.272001873 Simplifying x + 7.5 = -4.272001873 Reorder the terms: 7.5 + x = -4.272001873 Solving 7.5 + x = -4.272001873 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + x = -4.272001873 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = -4.272001873 + -7.5 x = -4.272001873 + -7.5 Combine like terms: -4.272001873 + -7.5 = -11.772001873 x = -11.772001873 Simplifying x = -11.772001873Solution
The solution to the problem is based on the solutions from the subproblems. x = {-3.227998127, -11.772001873}
