Begin completing the square. Divide all terms by 9 the coefficient of the squared term: Divide each side by '9'. 0.8888888889 + -0.2222222222v + v2 = 0 Move the constant term to the right: Add '-0.8888888889' to each side of the equation. 0.8888888889 + -0.2222222222v + -0.8888888889 + v2 = 0 + -0.8888888889 Reorder the terms: 0.8888888889 + -0.8888888889 + -0.2222222222v + v2 = 0 + -0.8888888889 Combine like terms: 0.8888888889 + -0.8888888889 = 0.0000000000 0.0000000000 + -0.2222222222v + v2 = 0 + -0.8888888889 -0.2222222222v + v2 = 0 + -0.8888888889 Combine like terms: 0 + -0.8888888889 = -0.8888888889 -0.2222222222v + v2 = -0.8888888889 The v term is -0.2222222222v. Take half its coefficient (-0.1111111111). Square it (0.01234567901) and add it to both sides. Add '0.01234567901' to each side of the equation. -0.2222222222v + 0.01234567901 + v2 = -0.8888888889 + 0.01234567901 Reorder the terms: 0.01234567901 + -0.2222222222v + v2 = -0.8888888889 + 0.01234567901 Combine like terms: -0.8888888889 + 0.01234567901 = -0.87654320989 0.01234567901 + -0.2222222222v + v2 = -0.87654320989 Factor a perfect square on the left side: (v + -0.1111111111)(v + -0.1111111111) = -0.87654320989 Can't calculate square root of the right side. The solution to this equation could not be determined.
