Subproblem 1

Set the factor '(-12 + -2n + n2)' equal to zero and attempt to solve: Simplifying -12 + -2n + n2 = 0 Solving -12 + -2n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '12' to each side of the equation. -12 + -2n + 12 + n2 = 0 + 12 Reorder the terms: -12 + 12 + -2n + n2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + -2n + n2 = 0 + 12 -2n + n2 = 0 + 12 Combine like terms: 0 + 12 = 12 -2n + n2 = 12 The n term is -2n. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2n + 1 + n2 = 12 + 1 Reorder the terms: 1 + -2n + n2 = 12 + 1 Combine like terms: 12 + 1 = 13 1 + -2n + n2 = 13 Factor a perfect square on the left side: (n + -1)(n + -1) = 13 Calculate the square root of the right side: 3.605551275 Break this problem into two subproblems by setting (n + -1) equal to 3.605551275 and -3.605551275.

Subproblem 1

n + -1 = 3.605551275 Simplifying n + -1 = 3.605551275 Reorder the terms: -1 + n = 3.605551275 Solving -1 + n = 3.605551275 Solving for variable 'n'.
