Simplifying -16k2 + -8k + -24 = 0 Reorder the terms: -24 + -8k + -16k2 = 0 Solving -24 + -8k + -16k2 = 0 Solving for variable 'k'. Factor out the Greatest Common Factor (GCF), '-8'. -8(3 + k + 2k2) = 0 Ignore the factor -8.Subproblem 1
Set the factor '(3 + k + 2k2)' equal to zero and attempt to solve: Simplifying 3 + k + 2k2 = 0 Solving 3 + k + 2k2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 1.5 + 0.5k + k2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + 0.5k + -1.5 + k2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + 0.5k + k2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + 0.5k + k2 = 0 + -1.5 0.5k + k2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 0.5k + k2 = -1.5 The k term is k. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.5k + 0.25 + k2 = -1.5 + 0.25 Reorder the terms: 0.25 + 0.5k + k2 = -1.5 + 0.25 Combine like terms: -1.5 + 0.25 = -1.25 0.25 + 0.5k + k2 = -1.25 Factor a perfect square on the left side: (k + 0.5)(k + 0.5) = -1.25 Can't calculate square root of the right side.
