Subproblem 1

Set the factor '(-11 + -4x + x2)' equal to zero and attempt to solve: Simplifying -11 + -4x + x2 = 0 Solving -11 + -4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '11' to each side of the equation. -11 + -4x + 11 + x2 = 0 + 11 Reorder the terms: -11 + 11 + -4x + x2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -4x + x2 = 0 + 11 -4x + x2 = 0 + 11 Combine like terms: 0 + 11 = 11 -4x + x2 = 11 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 11 + 4 Reorder the terms: 4 + -4x + x2 = 11 + 4 Combine like terms: 11 + 4 = 15 4 + -4x + x2 = 15 Factor a perfect square on the left side: (x + -2)(x + -2) = 15 Calculate the square root of the right side: 3.872983346 Break this problem into two subproblems by setting (x + -2) equal to 3.872983346 and -3.872983346.
