Simplifying x2 + -6 = -7x Reorder the terms: -6 + x2 = -7x Solving -6 + x2 = -7x Solving for variable 'x'. Reorder the terms: -6 + 7x + x2 = -7x + 7x Combine like terms: -7x + 7x = 0 -6 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '6' to each side of the equation. -6 + 7x + 6 + x2 = 0 + 6 Reorder the terms: -6 + 6 + 7x + x2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + 7x + x2 = 0 + 6 7x + x2 = 0 + 6 Combine like terms: 0 + 6 = 6 7x + x2 = 6 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 = 6 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 6 + 12.25 Combine like terms: 6 + 12.25 = 18.25 12.25 + 7x + x2 = 18.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 18.25 Calculate the square root of the right side: 4.272001873 Break this problem into two subproblems by setting (x + 3.5) equal to 4.272001873 and -4.272001873.Subproblem 1
x + 3.5 = 4.272001873 Simplifying x + 3.5 = 4.272001873 Reorder the terms: 3.5 + x = 4.272001873 Solving 3.5 + x = 4.272001873 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 = 4.272001873 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 4.272001873 + -3.5 x = 4.272001873 + -3.5 Combine like terms: 4.272001873 + -3.5 = 0.772001873 x = 0.772001873 Simplifying x = 0.772001873Subproblem 2
x + 3.5 = -4.272001873 Simplifying x + 3.5 = -4.272001873 Reorder the terms: 3.5 + x = -4.272001873 Solving 3.5 + x = -4.272001873 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 = -4.272001873 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -4.272001873 + -3.5 x = -4.272001873 + -3.5 Combine like terms: -4.272001873 + -3.5 = -7.772001873 x = -7.772001873 Simplifying x = -7.772001873Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.772001873, -7.772001873}
