Simplifying 4n2 + -10n + 18 = 9 Reorder the terms: 18 + -10n + 4n2 = 9 Solving 18 + -10n + 4n2 = 9 Solving for variable 'n'. Reorder the terms: 18 + -9 + -10n + 4n2 = 9 + -9 Combine like terms: 18 + -9 = 9 9 + -10n + 4n2 = 9 + -9 Combine like terms: 9 + -9 = 0 9 + -10n + 4n2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 2.25 + -2.5n + n2 = 0 Move the constant term to the right: Add '-2.25' to each side of the equation. 2.25 + -2.5n + -2.25 + n2 = 0 + -2.25 Reorder the terms: 2.25 + -2.25 + -2.5n + n2 = 0 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + -2.5n + n2 = 0 + -2.25 -2.5n + n2 = 0 + -2.25 Combine like terms: 0 + -2.25 = -2.25 -2.5n + n2 = -2.25 The n term is -2.5n. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5n + 1.5625 + n2 = -2.25 + 1.5625 Reorder the terms: 1.5625 + -2.5n + n2 = -2.25 + 1.5625 Combine like terms: -2.25 + 1.5625 = -0.6875 1.5625 + -2.5n + n2 = -0.6875 Factor a perfect square on the left side: (n + -1.25)(n + -1.25) = -0.6875 Can't calculate square root of the right side. The solution to this equation could not be determined.
