Simplifying 2K(K + 3) = -9 Reorder the terms: 2K(3 + K) = -9 (3 * 2K + K * 2K) = -9 (6K + 2K2) = -9 Solving 6K + 2K2 = -9 Solving for variable 'K'. Reorder the terms: 9 + 6K + 2K2 = -9 + 9 Combine like terms: -9 + 9 = 0 9 + 6K + 2K2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 4.5 + 3K + K2 = 0 Move the constant term to the right: Add '-4.5' to each side of the equation. 4.5 + 3K + -4.5 + K2 = 0 + -4.5 Reorder the terms: 4.5 + -4.5 + 3K + K2 = 0 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + 3K + K2 = 0 + -4.5 3K + K2 = 0 + -4.5 Combine like terms: 0 + -4.5 = -4.5 3K + K2 = -4.5 The K term is 3K. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3K + 2.25 + K2 = -4.5 + 2.25 Reorder the terms: 2.25 + 3K + K2 = -4.5 + 2.25 Combine like terms: -4.5 + 2.25 = -2.25 2.25 + 3K + K2 = -2.25 Factor a perfect square on the left side: (K + 1.5)(K + 1.5) = -2.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
