Simplifying 2k2 + -11k + -5 = 0 Reorder the terms: -5 + -11k + 2k2 = 0 Solving -5 + -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'. -2.5 + -5.5k + k2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + -5.5k + 2.5 + k2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + -5.5k + k2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + -5.5k + k2 = 0 + 2.5 -5.5k + k2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 -5.5k + k2 = 2.5 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 = 2.5 + 7.5625 Reorder the terms: 7.5625 + -5.5k + k2 = 2.5 + 7.5625 Combine like terms: 2.5 + 7.5625 = 10.0625 7.5625 + -5.5k + k2 = 10.0625 Factor a perfect square on the left side: (k + -2.75)(k + -2.75) = 10.0625 Calculate the square root of the right side: 3.172144385 Break this problem into two subproblems by setting (k + -2.75) equal to 3.172144385 and -3.172144385.Subproblem 1
k + -2.75 = 3.172144385 Simplifying k + -2.75 = 3.172144385 Reorder the terms: -2.75 + k = 3.172144385 Solving -2.75 + k = 3.172144385 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + k = 3.172144385 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + k = 3.172144385 + 2.75 k = 3.172144385 + 2.75 Combine like terms: 3.172144385 + 2.75 = 5.922144385 k = 5.922144385 Simplifying k = 5.922144385Subproblem 2
k + -2.75 = -3.172144385 Simplifying k + -2.75 = -3.172144385 Reorder the terms: -2.75 + k = -3.172144385 Solving -2.75 + k = -3.172144385 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + k = -3.172144385 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + k = -3.172144385 + 2.75 k = -3.172144385 + 2.75 Combine like terms: -3.172144385 + 2.75 = -0.422144385 k = -0.422144385 Simplifying k = -0.422144385Solution
