Simplifying x2 = -15x + -23 Reorder the terms: x2 = -23 + -15x Solving x2 = -23 + -15x Solving for variable 'x'. Reorder the terms: 23 + 15x + x2 = -23 + -15x + 23 + 15x Reorder the terms: 23 + 15x + x2 = -23 + 23 + -15x + 15x Combine like terms: -23 + 23 = 0 23 + 15x + x2 = 0 + -15x + 15x 23 + 15x + x2 = -15x + 15x Combine like terms: -15x + 15x = 0 23 + 15x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-23' to each side of the equation. 23 + 15x + -23 + x2 = 0 + -23 Reorder the terms: 23 + -23 + 15x + x2 = 0 + -23 Combine like terms: 23 + -23 = 0 0 + 15x + x2 = 0 + -23 15x + x2 = 0 + -23 Combine like terms: 0 + -23 = -23 15x + x2 = -23 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 = -23 + 56.25 Reorder the terms: 56.25 + 15x + x2 = -23 + 56.25 Combine like terms: -23 + 56.25 = 33.25 56.25 + 15x + x2 = 33.25 Factor a perfect square on the left side: (x + 7.5)(x + 7.5) = 33.25 Calculate the square root of the right side: 5.766281297 Break this problem into two subproblems by setting (x + 7.5) equal to 5.766281297 and -5.766281297.Subproblem 1
x + 7.5 = 5.766281297 Simplifying x + 7.5 = 5.766281297 Reorder the terms: 7.5 + x = 5.766281297 Solving 7.5 + x = 5.766281297 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 = 5.766281297 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = 5.766281297 + -7.5 x = 5.766281297 + -7.5 Combine like terms: 5.766281297 + -7.5 = -1.733718703 x = -1.733718703 Simplifying x = -1.733718703Subproblem 2
x + 7.5 = -5.766281297 Simplifying x + 7.5 = -5.766281297 Reorder the terms: 7.5 + x = -5.766281297 Solving 7.5 + x = -5.766281297 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 = -5.766281297 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = -5.766281297 + -7.5 x = -5.766281297 + -7.5 Combine like terms: -5.766281297 + -7.5 = -13.266281297 x = -13.266281297 Simplifying x = -13.266281297Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.733718703, -13.266281297}
