Subproblem 1

Set the factor '(6 + -11x + x2)' equal to zero and attempt to solve: Simplifying 6 + -11x + x2 = 0 Solving 6 + -11x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-6' to each side of the equation. 6 + -11x + -6 + x2 = 0 + -6 Reorder the terms: 6 + -6 + -11x + x2 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -11x + x2 = 0 + -6 -11x + x2 = 0 + -6 Combine like terms: 0 + -6 = -6 -11x + x2 = -6 The x term is -11x. Take half its coefficient (-5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. -11x + 30.25 + x2 = -6 + 30.25 Reorder the terms: 30.25 + -11x + x2 = -6 + 30.25 Combine like terms: -6 + 30.25 = 24.25 30.25 + -11x + x2 = 24.25 Factor a perfect square on the left side: (x + -5.5)(x + -5.5) = 24.25 Calculate the square root of the right side: 4.924428901 Break this problem into two subproblems by setting (x + -5.5) equal to 4.924428901 and -4.924428901.

Subproblem 1

x + -5.5 = 4.924428901 Simplifying x + -5.5 = 4.924428901 Reorder the terms: -5.5 + x = 4.924428901 Solving -5.5 + x = 4.924428901 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + x = 4.924428901 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + x = 4.924428901 + 5.5 x = 4.924428901 + 5.5 Combine like terms: 4.924428901 + 5.5 = 10.424428901 x = 10.424428901 Simplifying x = 10.424428901

Subproblem 2

x + -5.5 = -4.924428901 Simplifying x + -5.5 = -4.924428901 Reorder the terms: -5.5 + x = -4.924428901 Solving -5.5 + x = -4.924428901 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + x = -4.924428901 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + x = -4.924428901 + 5.5 x = -4.924428901 + 5.5 Combine like terms: -4.924428901 + 5.5 = 0.575571099 x = 0.575571099 Simplifying x = 0.575571099
