Simplifying x(x + 7) + -5 = 0 Reorder the terms: x(7 + x) + -5 = 0 (7 * x + x * x) + -5 = 0 (7x + x2) + -5 = 0 Reorder the terms: -5 + 7x + x2 = 0 Solving -5 + 7x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + 7x + 5 + x2 = 0 + 5 Reorder the terms: -5 + 5 + 7x + x2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 7x + x2 = 0 + 5 7x + x2 = 0 + 5 Combine like terms: 0 + 5 = 5 7x + x2 = 5 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 = 5 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 5 + 12.25 Combine like terms: 5 + 12.25 = 17.25 12.25 + 7x + x2 = 17.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 17.25 Calculate the square root of the right side: 4.153311931 Break this problem into two subproblems by setting (x + 3.5) equal to 4.153311931 and -4.153311931.Subproblem 1
x + 3.5 = 4.153311931 Simplifying x + 3.5 = 4.153311931 Reorder the terms: 3.5 + x = 4.153311931 Solving 3.5 + x = 4.153311931 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 = 4.153311931 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 4.153311931 + -3.5 x = 4.153311931 + -3.5 Combine like terms: 4.153311931 + -3.5 = 0.653311931 x = 0.653311931 Simplifying x = 0.653311931Subproblem 2
x + 3.5 = -4.153311931 Simplifying x + 3.5 = -4.153311931 Reorder the terms: 3.5 + x = -4.153311931 Solving 3.5 + x = -4.153311931 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 = -4.153311931 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -4.153311931 + -3.5 x = -4.153311931 + -3.5 Combine like terms: -4.153311931 + -3.5 = -7.653311931 x = -7.653311931 Simplifying x = -7.653311931Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.653311931, -7.653311931}
