Simplifying 4n2 + 3n + 6 = 0 Reorder the terms: 6 + 3n + 4n2 = 0 Solving 6 + 3n + 4n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.5 + 0.75n + n2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + 0.75n + -1.5 + n2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + 0.75n + n2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + 0.75n + n2 = 0 + -1.5 0.75n + n2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 0.75n + n2 = -1.5 The n term is 0.75n. Take half its coefficient (0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. 0.75n + 0.140625 + n2 = -1.5 + 0.140625 Reorder the terms: 0.140625 + 0.75n + n2 = -1.5 + 0.140625 Combine like terms: -1.5 + 0.140625 = -1.359375 0.140625 + 0.75n + n2 = -1.359375 Factor a perfect square on the left side: (n + 0.375)(n + 0.375) = -1.359375 Can't calculate square root of the right side. The solution to this equation could not be determined.
