Simplifying x2 + 7x + -77 = 0 Reorder the terms: -77 + 7x + x2 = 0 Solving -77 + 7x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '77' to each side of the equation. -77 + 7x + 77 + x2 = 0 + 77 Reorder the terms: -77 + 77 + 7x + x2 = 0 + 77 Combine like terms: -77 + 77 = 0 0 + 7x + x2 = 0 + 77 7x + x2 = 0 + 77 Combine like terms: 0 + 77 = 77 7x + x2 = 77 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 = 77 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 77 + 12.25 Combine like terms: 77 + 12.25 = 89.25 12.25 + 7x + x2 = 89.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 89.25 Calculate the square root of the right side: 9.447221814 Break this problem into two subproblems by setting (x + 3.5) equal to 9.447221814 and -9.447221814.Subproblem 1
x + 3.5 = 9.447221814 Simplifying x + 3.5 = 9.447221814 Reorder the terms: 3.5 + x = 9.447221814 Solving 3.5 + x = 9.447221814 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 = 9.447221814 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 9.447221814 + -3.5 x = 9.447221814 + -3.5 Combine like terms: 9.447221814 + -3.5 = 5.947221814 x = 5.947221814 Simplifying x = 5.947221814Subproblem 2
x + 3.5 = -9.447221814 Simplifying x + 3.5 = -9.447221814 Reorder the terms: 3.5 + x = -9.447221814 Solving 3.5 + x = -9.447221814 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 = -9.447221814 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -9.447221814 + -3.5 x = -9.447221814 + -3.5 Combine like terms: -9.447221814 + -3.5 = -12.947221814 x = -12.947221814 Simplifying x = -12.947221814Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.947221814, -12.947221814}
