Simplifying 2k + -1 = (k2 + -7) + -3k + -4 Reorder the terms: -1 + 2k = (k2 + -7) + -3k + -4 Reorder the terms: -1 + 2k = (-7 + k2) + -3k + -4 Remove parenthesis around (-7 + k2) -1 + 2k = -7 + k2 + -3k + -4 Reorder the terms: -1 + 2k = -7 + -4 + -3k + k2 Combine like terms: -7 + -4 = -11 -1 + 2k = -11 + -3k + k2 Solving -1 + 2k = -11 + -3k + k2 Solving for variable 'k'. Reorder the terms: -1 + 11 + 2k + 3k + -1k2 = -11 + -3k + k2 + 11 + 3k + -1k2 Combine like terms: -1 + 11 = 10 10 + 2k + 3k + -1k2 = -11 + -3k + k2 + 11 + 3k + -1k2 Combine like terms: 2k + 3k = 5k 10 + 5k + -1k2 = -11 + -3k + k2 + 11 + 3k + -1k2 Reorder the terms: 10 + 5k + -1k2 = -11 + 11 + -3k + 3k + k2 + -1k2 Combine like terms: -11 + 11 = 0 10 + 5k + -1k2 = 0 + -3k + 3k + k2 + -1k2 10 + 5k + -1k2 = -3k + 3k + k2 + -1k2 Combine like terms: -3k + 3k = 0 10 + 5k + -1k2 = 0 + k2 + -1k2 10 + 5k + -1k2 = k2 + -1k2 Combine like terms: k2 + -1k2 = 0 10 + 5k + -1k2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -10 + -5k + k2 = 0 Move the constant term to the right: Add '10' to each side of the equation. -10 + -5k + 10 + k2 = 0 + 10 Reorder the terms: -10 + 10 + -5k + k2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -5k + k2 = 0 + 10 -5k + k2 = 0 + 10 Combine like terms: 0 + 10 = 10 -5k + k2 = 10 The k term is -5k. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5k + 6.25 + k2 = 10 + 6.25 Reorder the terms: 6.25 + -5k + k2 = 10 + 6.25 Combine like terms: 10 + 6.25 = 16.25 6.25 + -5k + k2 = 16.25 Factor a perfect square on the left side: (k + -2.5)(k + -2.5) = 16.25 Calculate the square root of the right side: 4.031128874 Break this problem into two subproblems by setting (k + -2.5) equal to 4.031128874 and -4.031128874.Subproblem 1
k + -2.5 = 4.031128874 Simplifying k + -2.5 = 4.031128874 Reorder the terms: -2.5 + k = 4.031128874 Solving -2.5 + k = 4.031128874 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + k = 4.031128874 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + k = 4.031128874 + 2.5 k = 4.031128874 + 2.5 Combine like terms: 4.031128874 + 2.5 = 6.531128874 k = 6.531128874 Simplifying k = 6.531128874Subproblem 2
k + -2.5 = -4.031128874 Simplifying k + -2.5 = -4.031128874 Reorder the terms: -2.5 + k = -4.031128874 Solving -2.5 + k = -4.031128874 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + k = -4.031128874 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + k = -4.031128874 + 2.5 k = -4.031128874 + 2.5 Combine like terms: -4.031128874 + 2.5 = -1.531128874 k = -1.531128874 Simplifying k = -1.531128874Solution
The solution to the problem is based on the solutions from the subproblems. k = {6.531128874, -1.531128874}
