Simplifying 2k2 + 11k + 30 = 0 Reorder the terms: 30 + 11k + 2k2 = 0 Solving 30 + 11k + 2k2 = 0 Solving for variable 'k'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 15 + 5.5k + k2 = 0 Move the constant term to the right: Add '-15' to each side of the equation. 15 + 5.5k + -15 + k2 = 0 + -15 Reorder the terms: 15 + -15 + 5.5k + k2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + 5.5k + k2 = 0 + -15 5.5k + k2 = 0 + -15 Combine like terms: 0 + -15 = -15 5.5k + k2 = -15 The k term is 5.5k. Take half its coefficient (2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. 5.5k + 7.5625 + k2 = -15 + 7.5625 Reorder the terms: 7.5625 + 5.5k + k2 = -15 + 7.5625 Combine like terms: -15 + 7.5625 = -7.4375 7.5625 + 5.5k + k2 = -7.4375 Factor a perfect square on the left side: (k + 2.75)(k + 2.75) = -7.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
