Simplifying x2 + 15x + 46 = 0 Reorder the terms: 46 + 15x + x2 = 0 Solving 46 + 15x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-46' to each side of the equation. 46 + 15x + -46 + x2 = 0 + -46 Reorder the terms: 46 + -46 + 15x + x2 = 0 + -46 Combine like terms: 46 + -46 = 0 0 + 15x + x2 = 0 + -46 15x + x2 = 0 + -46 Combine like terms: 0 + -46 = -46 15x + x2 = -46 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 = -46 + 56.25 Reorder the terms: 56.25 + 15x + x2 = -46 + 56.25 Combine like terms: -46 + 56.25 = 10.25 56.25 + 15x + x2 = 10.25 Factor a perfect square on the left side: (x + 7.5)(x + 7.5) = 10.25 Calculate the square root of the right side: 3.201562119 Break this problem into two subproblems by setting (x + 7.5) equal to 3.201562119 and -3.201562119.Subproblem 1
x + 7.5 = 3.201562119 Simplifying x + 7.5 = 3.201562119 Reorder the terms: 7.5 + x = 3.201562119 Solving 7.5 + x = 3.201562119 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 = 3.201562119 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = 3.201562119 + -7.5 x = 3.201562119 + -7.5 Combine like terms: 3.201562119 + -7.5 = -4.298437881 x = -4.298437881 Simplifying x = -4.298437881Subproblem 2
x + 7.5 = -3.201562119 Simplifying x + 7.5 = -3.201562119 Reorder the terms: 7.5 + x = -3.201562119 Solving 7.5 + x = -3.201562119 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 = -3.201562119 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = -3.201562119 + -7.5 x = -3.201562119 + -7.5 Combine like terms: -3.201562119 + -7.5 = -10.701562119 x = -10.701562119 Simplifying x = -10.701562119Solution
The solution to the problem is based on the solutions from the subproblems. x = {-4.298437881, -10.701562119}
