Simplifying x2 + 6x + 10 = 15 Reorder the terms: 10 + 6x + x2 = 15 Solving 10 + 6x + x2 = 15 Solving for variable 'x'. Reorder the terms: 10 + -15 + 6x + x2 = 15 + -15 Combine like terms: 10 + -15 = -5 -5 + 6x + x2 = 15 + -15 Combine like terms: 15 + -15 = 0 -5 + 6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + 6x + 5 + x2 = 0 + 5 Reorder the terms: -5 + 5 + 6x + x2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 6x + x2 = 0 + 5 6x + x2 = 0 + 5 Combine like terms: 0 + 5 = 5 6x + x2 = 5 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = 5 + 9 Reorder the terms: 9 + 6x + x2 = 5 + 9 Combine like terms: 5 + 9 = 14 9 + 6x + x2 = 14 Factor a perfect square on the left side: (x + 3)(x + 3) = 14 Calculate the square root of the right side: 3.741657387 Break this problem into two subproblems by setting (x + 3) equal to 3.741657387 and -3.741657387.Subproblem 1
x + 3 = 3.741657387 Simplifying x + 3 = 3.741657387 Reorder the terms: 3 + x = 3.741657387 Solving 3 + x = 3.741657387 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 3.741657387 + -3 Combine like terms: 3 + -3 = 0 0 + x = 3.741657387 + -3 x = 3.741657387 + -3 Combine like terms: 3.741657387 + -3 = 0.741657387 x = 0.741657387 Simplifying x = 0.741657387Subproblem 2
x + 3 = -3.741657387 Simplifying x + 3 = -3.741657387 Reorder the terms: 3 + x = -3.741657387 Solving 3 + x = -3.741657387 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -3.741657387 + -3 Combine like terms: 3 + -3 = 0 0 + x = -3.741657387 + -3 x = -3.741657387 + -3 Combine like terms: -3.741657387 + -3 = -6.741657387 x = -6.741657387 Simplifying x = -6.741657387Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.741657387, -6.741657387}
