Subproblem 1

Set the factor '(43 + 4n + n2)' equal to zero and attempt to solve: Simplifying 43 + 4n + n2 = 0 Solving 43 + 4n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '-43' to each side of the equation. 43 + 4n + -43 + n2 = 0 + -43 Reorder the terms: 43 + -43 + 4n + n2 = 0 + -43 Combine like terms: 43 + -43 = 0 0 + 4n + n2 = 0 + -43 4n + n2 = 0 + -43 Combine like terms: 0 + -43 = -43 4n + n2 = -43 The n term is 4n. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4n + 4 + n2 = -43 + 4 Reorder the terms: 4 + 4n + n2 = -43 + 4 Combine like terms: -43 + 4 = -39 4 + 4n + n2 = -39 Factor a perfect square on the left side: (n + 2)(n + 2) = -39 Can't calculate square root of the right side.
