Simplifying 2k2 + k + -7 = 0 Reorder the terms: -7 + k + 2k2 = 0 Solving -7 + k + 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'. -3.5 + 0.5k + k2 = 0 Move the constant term to the right: Add '3.5' to each side of the equation. -3.5 + 0.5k + 3.5 + k2 = 0 + 3.5 Reorder the terms: -3.5 + 3.5 + 0.5k + k2 = 0 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + 0.5k + k2 = 0 + 3.5 0.5k + k2 = 0 + 3.5 Combine like terms: 0 + 3.5 = 3.5 0.5k + k2 = 3.5 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 = 3.5 + 0.25 Reorder the terms: 0.25 + 0.5k + k2 = 3.5 + 0.25 Combine like terms: 3.5 + 0.25 = 3.75 0.25 + 0.5k + k2 = 3.75 Factor a perfect square on the left side: (k + 0.5)(k + 0.5) = 3.75 Calculate the square root of the right side: 1.936491673 Break this problem into two subproblems by setting (k + 0.5) equal to 1.936491673 and -1.936491673.Subproblem 1
k + 0.5 = 1.936491673 Simplifying k + 0.5 = 1.936491673 Reorder the terms: 0.5 + k = 1.936491673 Solving 0.5 + k = 1.936491673 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + k = 1.936491673 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + k = 1.936491673 + -0.5 k = 1.936491673 + -0.5 Combine like terms: 1.936491673 + -0.5 = 1.436491673 k = 1.436491673 Simplifying k = 1.436491673Subproblem 2
k + 0.5 = -1.936491673 Simplifying k + 0.5 = -1.936491673 Reorder the terms: 0.5 + k = -1.936491673 Solving 0.5 + k = -1.936491673 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + k = -1.936491673 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + k = -1.936491673 + -0.5 k = -1.936491673 + -0.5 Combine like terms: -1.936491673 + -0.5 = -2.436491673 k = -2.436491673 Simplifying k = -2.436491673Solution
