Simplifying -6d2 + 9d + -2 = 0 Reorder the terms: -2 + 9d + -6d2 = 0 Solving -2 + 9d + -6d2 = 0 Solving for variable 'd'. Begin completing the square. Divide all terms by -6 the coefficient of the squared term: Divide each side by '-6'. 0.3333333333 + -1.5d + d2 = 0 Move the constant term to the right: Add '-0.3333333333' to each side of the equation. 0.3333333333 + -1.5d + -0.3333333333 + d2 = 0 + -0.3333333333 Reorder the terms: 0.3333333333 + -0.3333333333 + -1.5d + d2 = 0 + -0.3333333333 Combine like terms: 0.3333333333 + -0.3333333333 = 0.0000000000 0.0000000000 + -1.5d + d2 = 0 + -0.3333333333 -1.5d + d2 = 0 + -0.3333333333 Combine like terms: 0 + -0.3333333333 = -0.3333333333 -1.5d + d2 = -0.3333333333 The d term is -1.5d. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5d + 0.5625 + d2 = -0.3333333333 + 0.5625 Reorder the terms: 0.5625 + -1.5d + d2 = -0.3333333333 + 0.5625 Combine like terms: -0.3333333333 + 0.5625 = 0.2291666667 0.5625 + -1.5d + d2 = 0.2291666667 Factor a perfect square on the left side: (d + -0.75)(d + -0.75) = 0.2291666667 Calculate the square root of the right side: 0.478713554 Break this problem into two subproblems by setting (d + -0.75) equal to 0.478713554 and -0.478713554.Subproblem 1
d + -0.75 = 0.478713554 Simplifying d + -0.75 = 0.478713554 Reorder the terms: -0.75 + d = 0.478713554 Solving -0.75 + d = 0.478713554 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + d = 0.478713554 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + d = 0.478713554 + 0.75 d = 0.478713554 + 0.75 Combine like terms: 0.478713554 + 0.75 = 1.228713554 d = 1.228713554 Simplifying d = 1.228713554Subproblem 2
d + -0.75 = -0.478713554 Simplifying d + -0.75 = -0.478713554 Reorder the terms: -0.75 + d = -0.478713554 Solving -0.75 + d = -0.478713554 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + d = -0.478713554 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + d = -0.478713554 + 0.75 d = -0.478713554 + 0.75 Combine like terms: -0.478713554 + 0.75 = 0.271286446 d = 0.271286446 Simplifying d = 0.271286446Solution
