Subproblem 1

Set the factor '(12 + 2k + 5k2)' equal to zero and attempt to solve: Simplifying 12 + 2k + 5k2 = 0 Solving 12 + 2k + 5k2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 2.4 + 0.4k + k2 = 0 Move the constant term to the right: Add '-2.4' to each side of the equation. 2.4 + 0.4k + -2.4 + k2 = 0 + -2.4 Reorder the terms: 2.4 + -2.4 + 0.4k + k2 = 0 + -2.4 Combine like terms: 2.4 + -2.4 = 0.0 0.0 + 0.4k + k2 = 0 + -2.4 0.4k + k2 = 0 + -2.4 Combine like terms: 0 + -2.4 = -2.4 0.4k + k2 = -2.4 The k term is 0.4k. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4k + 0.04 + k2 = -2.4 + 0.04 Reorder the terms: 0.04 + 0.4k + k2 = -2.4 + 0.04 Combine like terms: -2.4 + 0.04 = -2.36 0.04 + 0.4k + k2 = -2.36 Factor a perfect square on the left side: (k + 0.2)(k + 0.2) = -2.36 Can't calculate square root of the right side.
