Simplifying 6d(d + -1) = 21 + -2 Reorder the terms: 6d(-1 + d) = 21 + -2 (-1 * 6d + d * 6d) = 21 + -2 (-6d + 6d2) = 21 + -2 Combine like terms: 21 + -2 = 19 -6d + 6d2 = 19 Solving -6d + 6d2 = 19 Solving for variable 'd'. Reorder the terms: -19 + -6d + 6d2 = 19 + -19 Combine like terms: 19 + -19 = 0 -19 + -6d + 6d2 = 0 Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. -3.166666667 + -1d + d2 = 0 Move the constant term to the right: Add '3.166666667' to each side of the equation. -3.166666667 + -1d + 3.166666667 + d2 = 0 + 3.166666667 Reorder the terms: -3.166666667 + 3.166666667 + -1d + d2 = 0 + 3.166666667 Combine like terms: -3.166666667 + 3.166666667 = 0.000000000 0.000000000 + -1d + d2 = 0 + 3.166666667 -1d + d2 = 0 + 3.166666667 Combine like terms: 0 + 3.166666667 = 3.166666667 -1d + d2 = 3.166666667 The d term is -1d. 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. -1d + 0.25 + d2 = 3.166666667 + 0.25 Reorder the terms: 0.25 + -1d + d2 = 3.166666667 + 0.25 Combine like terms: 3.166666667 + 0.25 = 3.416666667 0.25 + -1d + d2 = 3.416666667 Factor a perfect square on the left side: (d + -0.5)(d + -0.5) = 3.416666667 Calculate the square root of the right side: 1.848422751 Break this problem into two subproblems by setting (d + -0.5) equal to 1.848422751 and -1.848422751.Subproblem 1
d + -0.5 = 1.848422751 Simplifying d + -0.5 = 1.848422751 Reorder the terms: -0.5 + d = 1.848422751 Solving -0.5 + d = 1.848422751 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + d = 1.848422751 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + d = 1.848422751 + 0.5 d = 1.848422751 + 0.5 Combine like terms: 1.848422751 + 0.5 = 2.348422751 d = 2.348422751 Simplifying d = 2.348422751Subproblem 2
d + -0.5 = -1.848422751 Simplifying d + -0.5 = -1.848422751 Reorder the terms: -0.5 + d = -1.848422751 Solving -0.5 + d = -1.848422751 Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + d = -1.848422751 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + d = -1.848422751 + 0.5 d = -1.848422751 + 0.5 Combine like terms: -1.848422751 + 0.5 = -1.348422751 d = -1.348422751 Simplifying d = -1.348422751Solution
The solution to the problem is based on the solutions from the subproblems. d = {2.348422751, -1.348422751}
