Simplifying 4k2 + -3k + -11 = 0 Reorder the terms: -11 + -3k + 4k2 = 0 Solving -11 + -3k + 4k2 = 0 Solving for variable 'k'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -2.75 + -0.75k + k2 = 0 Move the constant term to the right: Add '2.75' to each side of the equation. -2.75 + -0.75k + 2.75 + k2 = 0 + 2.75 Reorder the terms: -2.75 + 2.75 + -0.75k + k2 = 0 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + -0.75k + k2 = 0 + 2.75 -0.75k + k2 = 0 + 2.75 Combine like terms: 0 + 2.75 = 2.75 -0.75k + k2 = 2.75 The k term is -0.75k. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75k + 0.140625 + k2 = 2.75 + 0.140625 Reorder the terms: 0.140625 + -0.75k + k2 = 2.75 + 0.140625 Combine like terms: 2.75 + 0.140625 = 2.890625 0.140625 + -0.75k + k2 = 2.890625 Factor a perfect square on the left side: (k + -0.375)(k + -0.375) = 2.890625 Calculate the square root of the right side: 1.700183814 Break this problem into two subproblems by setting (k + -0.375) equal to 1.700183814 and -1.700183814.Subproblem 1
k + -0.375 = 1.700183814 Simplifying k + -0.375 = 1.700183814 Reorder the terms: -0.375 + k = 1.700183814 Solving -0.375 + k = 1.700183814 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + k = 1.700183814 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + k = 1.700183814 + 0.375 k = 1.700183814 + 0.375 Combine like terms: 1.700183814 + 0.375 = 2.075183814 k = 2.075183814 Simplifying k = 2.075183814Subproblem 2
k + -0.375 = -1.700183814 Simplifying k + -0.375 = -1.700183814 Reorder the terms: -0.375 + k = -1.700183814 Solving -0.375 + k = -1.700183814 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + k = -1.700183814 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + k = -1.700183814 + 0.375 k = -1.700183814 + 0.375 Combine like terms: -1.700183814 + 0.375 = -1.325183814 k = -1.325183814 Simplifying k = -1.325183814Solution
