Simplifying 20v2 + -39vd + 18d2 = 0 Reorder the terms: -39dv + 18d2 + 20v2 = 0 Solving -39dv + 18d2 + 20v2 = 0 Solving for variable 'd'. Factor a trinomial. (3d + -4v)(6d + -5v) = 0Subproblem 1
Set the factor '(3d + -4v)' equal to zero and attempt to solve: Simplifying 3d + -4v = 0 Solving 3d + -4v = 0 Move all terms containing d to the left, all other terms to the right. Add '4v' to each side of the equation. 3d + -4v + 4v = 0 + 4v Combine like terms: -4v + 4v = 0 3d + 0 = 0 + 4v 3d = 0 + 4v Remove the zero: 3d = 4v Divide each side by '3'. d = 1.333333333v Simplifying d = 1.333333333vSubproblem 2
Set the factor '(6d + -5v)' equal to zero and attempt to solve: Simplifying 6d + -5v = 0 Solving 6d + -5v = 0 Move all terms containing d to the left, all other terms to the right. Add '5v' to each side of the equation. 6d + -5v + 5v = 0 + 5v Combine like terms: -5v + 5v = 0 6d + 0 = 0 + 5v 6d = 0 + 5v Remove the zero: 6d = 5v Divide each side by '6'. d = 0.8333333333v Simplifying d = 0.8333333333vSolution
d = {1.333333333v, 0.8333333333v}
