Subproblem 1

Set the factor '(11 + 10x2 + x4)' equal to zero and attempt to solve: Simplifying 11 + 10x2 + x4 = 0 Solving 11 + 10x2 + x4 = 0 Begin completing the square. Move the constant term to the right: Add '-11' to each side of the equation. 11 + 10x2 + -11 + x4 = 0 + -11 Reorder the terms: 11 + -11 + 10x2 + x4 = 0 + -11 Combine like terms: 11 + -11 = 0 0 + 10x2 + x4 = 0 + -11 10x2 + x4 = 0 + -11 Combine like terms: 0 + -11 = -11 10x2 + x4 = -11 The x term is 10x2. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10x2 + 25 + x4 = -11 + 25 Reorder the terms: 25 + 10x2 + x4 = -11 + 25 Combine like terms: -11 + 25 = 14 25 + 10x2 + x4 = 14 Factor a perfect square on the left side: (x2 + 5)(x2 + 5) = 14 Calculate the square root of the right side: 3.741657387 Break this problem into two subproblems by setting (x2 + 5) equal to 3.741657387 and -3.741657387.
