Subproblem 1

Set the factor '(-6 + -2x + x2)' equal to zero and attempt to solve: Simplifying -6 + -2x + x2 = 0 Solving -6 + -2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '6' to each side of the equation. -6 + -2x + 6 + x2 = 0 + 6 Reorder the terms: -6 + 6 + -2x + x2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + -2x + x2 = 0 + 6 -2x + x2 = 0 + 6 Combine like terms: 0 + 6 = 6 -2x + x2 = 6 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 6 + 1 Reorder the terms: 1 + -2x + x2 = 6 + 1 Combine like terms: 6 + 1 = 7 1 + -2x + x2 = 7 Factor a perfect square on the left side: (x + -1)(x + -1) = 7 Calculate the square root of the right side: 2.645751311 Break this problem into two subproblems by setting (x + -1) equal to 2.645751311 and -2.645751311.

Subproblem 1

x + -1 = 2.645751311 Simplifying x + -1 = 2.645751311 Reorder the terms: -1 + x = 2.645751311 Solving -1 + x = 2.645751311 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 2.645751311 + 1 Combine like terms: -1 + 1 = 0 0 + x = 2.645751311 + 1 x = 2.645751311 + 1 Combine like terms: 2.645751311 + 1 = 3.645751311 x = 3.645751311 Simplifying x = 3.645751311
