Subproblem 1

Set the factor '(-62 + 7x + x2)' equal to zero and attempt to solve: Simplifying -62 + 7x + x2 = 0 Solving -62 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '62' to each side of the equation. -62 + 7x + 62 + x2 = 0 + 62 Reorder the terms: -62 + 62 + 7x + x2 = 0 + 62 Combine like terms: -62 + 62 = 0 0 + 7x + x2 = 0 + 62 7x + x2 = 0 + 62 Combine like terms: 0 + 62 = 62 7x + x2 = 62 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 = 62 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 62 + 12.25 Combine like terms: 62 + 12.25 = 74.25 12.25 + 7x + x2 = 74.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 74.25 Calculate the square root of the right side: 8.61684397 Break this problem into two subproblems by setting (x + 3.5) equal to 8.61684397 and -8.61684397.

Subproblem 1
