Simplifying x + x2 + -7x = 77 Reorder the terms: x + -7x + x2 = 77 Combine like terms: x + -7x = -6x -6x + x2 = 77 Solving -6x + x2 = 77 Solving for variable 'x'. Reorder the terms: -77 + -6x + x2 = 77 + -77 Combine like terms: 77 + -77 = 0 -77 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '77' to each side of the equation. -77 + -6x + 77 + x2 = 0 + 77 Reorder the terms: -77 + 77 + -6x + x2 = 0 + 77 Combine like terms: -77 + 77 = 0 0 + -6x + x2 = 0 + 77 -6x + x2 = 0 + 77 Combine like terms: 0 + 77 = 77 -6x + x2 = 77 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 = 77 + 9 Reorder the terms: 9 + -6x + x2 = 77 + 9 Combine like terms: 77 + 9 = 86 9 + -6x + x2 = 86 Factor a perfect square on the left side: (x + -3)(x + -3) = 86 Calculate the square root of the right side: 9.273618495 Break this problem into two subproblems by setting (x + -3) equal to 9.273618495 and -9.273618495.Subproblem 1
x + -3 = 9.273618495 Simplifying x + -3 = 9.273618495 Reorder the terms: -3 + x = 9.273618495 Solving -3 + x = 9.273618495 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 = 9.273618495 + 3 Combine like terms: -3 + 3 = 0 0 + x = 9.273618495 + 3 x = 9.273618495 + 3 Combine like terms: 9.273618495 + 3 = 12.273618495 x = 12.273618495 Simplifying x = 12.273618495Subproblem 2
x + -3 = -9.273618495 Simplifying x + -3 = -9.273618495 Reorder the terms: -3 + x = -9.273618495 Solving -3 + x = -9.273618495 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 = -9.273618495 + 3 Combine like terms: -3 + 3 = 0 0 + x = -9.273618495 + 3 x = -9.273618495 + 3 Combine like terms: -9.273618495 + 3 = -6.273618495 x = -6.273618495 Simplifying x = -6.273618495Solution
The solution to the problem is based on the solutions from the subproblems. x = {12.273618495, -6.273618495}
