Subproblem 1

Set the factor '(-11 + -6x + x2)' equal to zero and attempt to solve: Simplifying -11 + -6x + x2 = 0 Solving -11 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '11' to each side of the equation. -11 + -6x + 11 + x2 = 0 + 11 Reorder the terms: -11 + 11 + -6x + x2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -6x + x2 = 0 + 11 -6x + x2 = 0 + 11 Combine like terms: 0 + 11 = 11 -6x + x2 = 11 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 = 11 + 9 Reorder the terms: 9 + -6x + x2 = 11 + 9 Combine like terms: 11 + 9 = 20 9 + -6x + x2 = 20 Factor a perfect square on the left side: (x + -3)(x + -3) = 20 Calculate the square root of the right side: 4.472135955 Break this problem into two subproblems by setting (x + -3) equal to 4.472135955 and -4.472135955.
