Subproblem 1

Set the factor '(39 + 10x + x2)' equal to zero and attempt to solve: Simplifying 39 + 10x + x2 = 0 Solving 39 + 10x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-39' to each side of the equation. 39 + 10x + -39 + x2 = 0 + -39 Reorder the terms: 39 + -39 + 10x + x2 = 0 + -39 Combine like terms: 39 + -39 = 0 0 + 10x + x2 = 0 + -39 10x + x2 = 0 + -39 Combine like terms: 0 + -39 = -39 10x + x2 = -39 The x term is 10x. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10x + 25 + x2 = -39 + 25 Reorder the terms: 25 + 10x + x2 = -39 + 25 Combine like terms: -39 + 25 = -14 25 + 10x + x2 = -14 Factor a perfect square on the left side: (x + 5)(x + 5) = -14 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
