Simplifying 6d2 + -13dt + -63t2 = 0 Reorder the terms: -13dt + 6d2 + -63t2 = 0 Solving -13dt + 6d2 + -63t2 = 0 Solving for variable 'd'. Factor a trinomial. (2d + -9t)(3d + 7t) = 0Subproblem 1
Set the factor '(2d + -9t)' equal to zero and attempt to solve: Simplifying 2d + -9t = 0 Solving 2d + -9t = 0 Move all terms containing d to the left, all other terms to the right. Add '9t' to each side of the equation. 2d + -9t + 9t = 0 + 9t Combine like terms: -9t + 9t = 0 2d + 0 = 0 + 9t 2d = 0 + 9t Remove the zero: 2d = 9t Divide each side by '2'. d = 4.5t Simplifying d = 4.5tSubproblem 2
Set the factor '(3d + 7t)' equal to zero and attempt to solve: Simplifying 3d + 7t = 0 Solving 3d + 7t = 0 Move all terms containing d to the left, all other terms to the right. Add '-7t' to each side of the equation. 3d + 7t + -7t = 0 + -7t Combine like terms: 7t + -7t = 0 3d + 0 = 0 + -7t 3d = 0 + -7t Remove the zero: 3d = -7t Divide each side by '3'. d = -2.333333333t Simplifying d = -2.333333333tSolution
d = {4.5t, -2.333333333t}
