Simplifying x2 + 2x + 5 = 50 Reorder the terms: 5 + 2x + x2 = 50 Solving 5 + 2x + x2 = 50 Solving for variable 'x'. Reorder the terms: 5 + -50 + 2x + x2 = 50 + -50 Combine like terms: 5 + -50 = -45 -45 + 2x + x2 = 50 + -50 Combine like terms: 50 + -50 = 0 -45 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '45' to each side of the equation. -45 + 2x + 45 + x2 = 0 + 45 Reorder the terms: -45 + 45 + 2x + x2 = 0 + 45 Combine like terms: -45 + 45 = 0 0 + 2x + x2 = 0 + 45 2x + x2 = 0 + 45 Combine like terms: 0 + 45 = 45 2x + x2 = 45 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 45 + 1 Reorder the terms: 1 + 2x + x2 = 45 + 1 Combine like terms: 45 + 1 = 46 1 + 2x + x2 = 46 Factor a perfect square on the left side: (x + 1)(x + 1) = 46 Calculate the square root of the right side: 6.782329983 Break this problem into two subproblems by setting (x + 1) equal to 6.782329983 and -6.782329983.Subproblem 1
x + 1 = 6.782329983 Simplifying x + 1 = 6.782329983 Reorder the terms: 1 + x = 6.782329983 Solving 1 + x = 6.782329983 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 6.782329983 + -1 Combine like terms: 1 + -1 = 0 0 + x = 6.782329983 + -1 x = 6.782329983 + -1 Combine like terms: 6.782329983 + -1 = 5.782329983 x = 5.782329983 Simplifying x = 5.782329983Subproblem 2
x + 1 = -6.782329983 Simplifying x + 1 = -6.782329983 Reorder the terms: 1 + x = -6.782329983 Solving 1 + x = -6.782329983 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -6.782329983 + -1 Combine like terms: 1 + -1 = 0 0 + x = -6.782329983 + -1 x = -6.782329983 + -1 Combine like terms: -6.782329983 + -1 = -7.782329983 x = -7.782329983 Simplifying x = -7.782329983Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.782329983, -7.782329983}
