Simplifying -6k2 + 3k + 4 = 0 Reorder the terms: 4 + 3k + -6k2 = 0 Solving 4 + 3k + -6k2 = 0 Solving for variable 'k'. Begin completing the square. Divide all terms by -6 the coefficient of the squared term: Divide each side by '-6'. -0.6666666667 + -0.5k + k2 = 0 Move the constant term to the right: Add '0.6666666667' to each side of the equation. -0.6666666667 + -0.5k + 0.6666666667 + k2 = 0 + 0.6666666667 Reorder the terms: -0.6666666667 + 0.6666666667 + -0.5k + k2 = 0 + 0.6666666667 Combine like terms: -0.6666666667 + 0.6666666667 = 0.0000000000 0.0000000000 + -0.5k + k2 = 0 + 0.6666666667 -0.5k + k2 = 0 + 0.6666666667 Combine like terms: 0 + 0.6666666667 = 0.6666666667 -0.5k + k2 = 0.6666666667 The k term is -0.5k. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5k + 0.0625 + k2 = 0.6666666667 + 0.0625 Reorder the terms: 0.0625 + -0.5k + k2 = 0.6666666667 + 0.0625 Combine like terms: 0.6666666667 + 0.0625 = 0.7291666667 0.0625 + -0.5k + k2 = 0.7291666667 Factor a perfect square on the left side: (k + -0.25)(k + -0.25) = 0.7291666667 Calculate the square root of the right side: 0.853912564 Break this problem into two subproblems by setting (k + -0.25) equal to 0.853912564 and -0.853912564.Subproblem 1
k + -0.25 = 0.853912564 Simplifying k + -0.25 = 0.853912564 Reorder the terms: -0.25 + k = 0.853912564 Solving -0.25 + k = 0.853912564 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + k = 0.853912564 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + k = 0.853912564 + 0.25 k = 0.853912564 + 0.25 Combine like terms: 0.853912564 + 0.25 = 1.103912564 k = 1.103912564 Simplifying k = 1.103912564Subproblem 2
k + -0.25 = -0.853912564 Simplifying k + -0.25 = -0.853912564 Reorder the terms: -0.25 + k = -0.853912564 Solving -0.25 + k = -0.853912564 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + k = -0.853912564 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + k = -0.853912564 + 0.25 k = -0.853912564 + 0.25 Combine like terms: -0.853912564 + 0.25 = -0.603912564 k = -0.603912564 Simplifying k = -0.603912564Solution
