Simplifying (x2) + -6x = -7.75 x2 + -6x = -7.75 Reorder the terms: -6x + x2 = -7.75 Solving -6x + x2 = -7.75 Solving for variable 'x'. Reorder the terms: 7.75 + -6x + x2 = -7.75 + 7.75 Combine like terms: -7.75 + 7.75 = 0.00 7.75 + -6x + x2 = 0.00 Begin completing the square. Move the constant term to the right: Add '-7.75' to each side of the equation. 7.75 + -6x + -7.75 + x2 = 0.00 + -7.75 Reorder the terms: 7.75 + -7.75 + -6x + x2 = 0.00 + -7.75 Combine like terms: 7.75 + -7.75 = 0.00 0.00 + -6x + x2 = 0.00 + -7.75 -6x + x2 = 0.00 + -7.75 Combine like terms: 0.00 + -7.75 = -7.75 -6x + x2 = -7.75 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 = -7.75 + 9 Reorder the terms: 9 + -6x + x2 = -7.75 + 9 Combine like terms: -7.75 + 9 = 1.25 9 + -6x + x2 = 1.25 Factor a perfect square on the left side: (x + -3)(x + -3) = 1.25 Calculate the square root of the right side: 1.118033989 Break this problem into two subproblems by setting (x + -3) equal to 1.118033989 and -1.118033989.Subproblem 1
x + -3 = 1.118033989 Simplifying x + -3 = 1.118033989 Reorder the terms: -3 + x = 1.118033989 Solving -3 + x = 1.118033989 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 = 1.118033989 + 3 Combine like terms: -3 + 3 = 0 0 + x = 1.118033989 + 3 x = 1.118033989 + 3 Combine like terms: 1.118033989 + 3 = 4.118033989 x = 4.118033989 Simplifying x = 4.118033989Subproblem 2
x + -3 = -1.118033989 Simplifying x + -3 = -1.118033989 Reorder the terms: -3 + x = -1.118033989 Solving -3 + x = -1.118033989 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 = -1.118033989 + 3 Combine like terms: -3 + 3 = 0 0 + x = -1.118033989 + 3 x = -1.118033989 + 3 Combine like terms: -1.118033989 + 3 = 1.881966011 x = 1.881966011 Simplifying x = 1.881966011Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.118033989, 1.881966011}
