Simplifying x2 + 7x + 10 = 31 Reorder the terms: 10 + 7x + x2 = 31 Solving 10 + 7x + x2 = 31 Solving for variable 'x'. Reorder the terms: 10 + -31 + 7x + x2 = 31 + -31 Combine like terms: 10 + -31 = -21 -21 + 7x + x2 = 31 + -31 Combine like terms: 31 + -31 = 0 -21 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '21' to each side of the equation. -21 + 7x + 21 + x2 = 0 + 21 Reorder the terms: -21 + 21 + 7x + x2 = 0 + 21 Combine like terms: -21 + 21 = 0 0 + 7x + x2 = 0 + 21 7x + x2 = 0 + 21 Combine like terms: 0 + 21 = 21 7x + x2 = 21 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = 21 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 21 + 12.25 Combine like terms: 21 + 12.25 = 33.25 12.25 + 7x + x2 = 33.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 33.25 Calculate the square root of the right side: 5.766281297 Break this problem into two subproblems by setting (x + 3.5) equal to 5.766281297 and -5.766281297.Subproblem 1
x + 3.5 = 5.766281297 Simplifying x + 3.5 = 5.766281297 Reorder the terms: 3.5 + x = 5.766281297 Solving 3.5 + x = 5.766281297 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = 5.766281297 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 5.766281297 + -3.5 x = 5.766281297 + -3.5 Combine like terms: 5.766281297 + -3.5 = 2.266281297 x = 2.266281297 Simplifying x = 2.266281297Subproblem 2
x + 3.5 = -5.766281297 Simplifying x + 3.5 = -5.766281297 Reorder the terms: 3.5 + x = -5.766281297 Solving 3.5 + x = -5.766281297 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = -5.766281297 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -5.766281297 + -3.5 x = -5.766281297 + -3.5 Combine like terms: -5.766281297 + -3.5 = -9.266281297 x = -9.266281297 Simplifying x = -9.266281297Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.266281297, -9.266281297}
