Simplifying 2n2 + 9n + 45 = 0 Reorder the terms: 45 + 9n + 2n2 = 0 Solving 45 + 9n + 2n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 22.5 + 4.5n + n2 = 0 Move the constant term to the right: Add '-22.5' to each side of the equation. 22.5 + 4.5n + -22.5 + n2 = 0 + -22.5 Reorder the terms: 22.5 + -22.5 + 4.5n + n2 = 0 + -22.5 Combine like terms: 22.5 + -22.5 = 0.0 0.0 + 4.5n + n2 = 0 + -22.5 4.5n + n2 = 0 + -22.5 Combine like terms: 0 + -22.5 = -22.5 4.5n + n2 = -22.5 The n term is 4.5n. Take half its coefficient (2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. 4.5n + 5.0625 + n2 = -22.5 + 5.0625 Reorder the terms: 5.0625 + 4.5n + n2 = -22.5 + 5.0625 Combine like terms: -22.5 + 5.0625 = -17.4375 5.0625 + 4.5n + n2 = -17.4375 Factor a perfect square on the left side: (n + 2.25)(n + 2.25) = -17.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
