Simplifying 3n2 + -1n = -6 Reorder the terms: -1n + 3n2 = -6 Solving -1n + 3n2 = -6 Solving for variable 'n'. Reorder the terms: 6 + -1n + 3n2 = -6 + 6 Combine like terms: -6 + 6 = 0 6 + -1n + 3n2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 2 + -0.3333333333n + n2 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + -0.3333333333n + -2 + n2 = 0 + -2 Reorder the terms: 2 + -2 + -0.3333333333n + n2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -0.3333333333n + n2 = 0 + -2 -0.3333333333n + n2 = 0 + -2 Combine like terms: 0 + -2 = -2 -0.3333333333n + n2 = -2 The n term is -0.3333333333n. Take half its coefficient (-0.1666666667). Square it (0.02777777779) and add it to both sides. Add '0.02777777779' to each side of the equation. -0.3333333333n + 0.02777777779 + n2 = -2 + 0.02777777779 Reorder the terms: 0.02777777779 + -0.3333333333n + n2 = -2 + 0.02777777779 Combine like terms: -2 + 0.02777777779 = -1.97222222221 0.02777777779 + -0.3333333333n + n2 = -1.97222222221 Factor a perfect square on the left side: (n + -0.1666666667)(n + -0.1666666667) = -1.97222222221 Can't calculate square root of the right side. The solution to this equation could not be determined.
