Simplifying 3n2 + 6n + 4 = 0 Reorder the terms: 4 + 6n + 3n2 = 0 Solving 4 + 6n + 3n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 1.333333333 + 2n + n2 = 0 Move the constant term to the right: Add '-1.333333333' to each side of the equation. 1.333333333 + 2n + -1.333333333 + n2 = 0 + -1.333333333 Reorder the terms: 1.333333333 + -1.333333333 + 2n + n2 = 0 + -1.333333333 Combine like terms: 1.333333333 + -1.333333333 = 0.000000000 0.000000000 + 2n + n2 = 0 + -1.333333333 2n + n2 = 0 + -1.333333333 Combine like terms: 0 + -1.333333333 = -1.333333333 2n + n2 = -1.333333333 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 = -1.333333333 + 1 Reorder the terms: 1 + 2n + n2 = -1.333333333 + 1 Combine like terms: -1.333333333 + 1 = -0.333333333 1 + 2n + n2 = -0.333333333 Factor a perfect square on the left side: (n + 1)(n + 1) = -0.333333333 Can't calculate square root of the right side. The solution to this equation could not be determined.
