Subproblem 1

Set the factor '(2 + 7x + x2)' equal to zero and attempt to solve: Simplifying 2 + 7x + x2 = 0 Solving 2 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + 7x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + 7x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 7x + x2 = 0 + -2 7x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 7x + x2 = -2 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = -2 + 12.25 Reorder the terms: 12.25 + 7x + x2 = -2 + 12.25 Combine like terms: -2 + 12.25 = 10.25 12.25 + 7x + x2 = 10.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 10.25 Calculate the square root of the right side: 3.201562119 Break this problem into two subproblems by setting (x + 3.5) equal to 3.201562119 and -3.201562119.
