Subproblem 1

Set the factor '(-4 + 11x + x2)' equal to zero and attempt to solve: Simplifying -4 + 11x + x2 = 0 Solving -4 + 11x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '4' to each side of the equation. -4 + 11x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + 11x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 11x + x2 = 0 + 4 11x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 11x + x2 = 4 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 = 4 + 30.25 Reorder the terms: 30.25 + 11x + x2 = 4 + 30.25 Combine like terms: 4 + 30.25 = 34.25 30.25 + 11x + x2 = 34.25 Factor a perfect square on the left side: (x + 5.5)(x + 5.5) = 34.25 Calculate the square root of the right side: 5.852349955 Break this problem into two subproblems by setting (x + 5.5) equal to 5.852349955 and -5.852349955.
