Subproblem 1

Set the factor '(-10 + 6n + -3n2)' equal to zero and attempt to solve: Simplifying -10 + 6n + -3n2 = 0 Solving -10 + 6n + -3n2 = 0 Begin completing the square. Divide all terms by -3 the coefficient of the squared term: Divide each side by '-3'. 3.333333333 + -2n + n2 = 0 Move the constant term to the right: Add '-3.333333333' to each side of the equation. 3.333333333 + -2n + -3.333333333 + n2 = 0 + -3.333333333 Reorder the terms: 3.333333333 + -3.333333333 + -2n + n2 = 0 + -3.333333333 Combine like terms: 3.333333333 + -3.333333333 = 0.000000000 0.000000000 + -2n + n2 = 0 + -3.333333333 -2n + n2 = 0 + -3.333333333 Combine like terms: 0 + -3.333333333 = -3.333333333 -2n + n2 = -3.333333333 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 = -3.333333333 + 1 Reorder the terms: 1 + -2n + n2 = -3.333333333 + 1 Combine like terms: -3.333333333 + 1 = -2.333333333 1 + -2n + n2 = -2.333333333 Factor a perfect square on the left side: (n + -1)(n + -1) = -2.333333333 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.
