Subproblem 1

Set the factor '(-3 + -6n + 4n2)' equal to zero and attempt to solve: Simplifying -3 + -6n + 4n2 = 0 Solving -3 + -6n + 4n2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -0.75 + -1.5n + n2 = 0 Move the constant term to the right: Add '0.75' to each side of the equation. -0.75 + -1.5n + 0.75 + n2 = 0 + 0.75 Reorder the terms: -0.75 + 0.75 + -1.5n + n2 = 0 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + -1.5n + n2 = 0 + 0.75 -1.5n + n2 = 0 + 0.75 Combine like terms: 0 + 0.75 = 0.75 -1.5n + n2 = 0.75 The n term is -1.5n. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5n + 0.5625 + n2 = 0.75 + 0.5625 Reorder the terms: 0.5625 + -1.5n + n2 = 0.75 + 0.5625 Combine like terms: 0.75 + 0.5625 = 1.3125 0.5625 + -1.5n + n2 = 1.3125 Factor a perfect square on the left side: (n + -0.75)(n + -0.75) = 1.3125 Calculate the square root of the right side: 1.145643924 Break this problem into two subproblems by setting (n + -0.75) equal to 1.145643924 and -1.145643924.

Subproblem 1
