Simplifying 2k2 + 13k + 57 = 0 Reorder the terms: 57 + 13k + 2k2 = 0 Solving 57 + 13k + 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'. 28.5 + 6.5k + k2 = 0 Move the constant term to the right: Add '-28.5' to each side of the equation. 28.5 + 6.5k + -28.5 + k2 = 0 + -28.5 Reorder the terms: 28.5 + -28.5 + 6.5k + k2 = 0 + -28.5 Combine like terms: 28.5 + -28.5 = 0.0 0.0 + 6.5k + k2 = 0 + -28.5 6.5k + k2 = 0 + -28.5 Combine like terms: 0 + -28.5 = -28.5 6.5k + k2 = -28.5 The k term is 6.5k. Take half its coefficient (3.25). Square it (10.5625) and add it to both sides. Add '10.5625' to each side of the equation. 6.5k + 10.5625 + k2 = -28.5 + 10.5625 Reorder the terms: 10.5625 + 6.5k + k2 = -28.5 + 10.5625 Combine like terms: -28.5 + 10.5625 = -17.9375 10.5625 + 6.5k + k2 = -17.9375 Factor a perfect square on the left side: (k + 3.25)(k + 3.25) = -17.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
