Solution for 5d(3-d)+d(2d-1)= equation:


Simplifying
5d(3 + -1d) + d(2d + -1) = 0
(3 * 5d + -1d * 5d) + d(2d + -1) = 0
(15d + -5d2) + d(2d + -1) = 0

Reorder the terms:
15d + -5d2 + d(-1 + 2d) = 0
15d + -5d2 + (-1 * d + 2d * d) = 0
15d + -5d2 + (-1d + 2d2) = 0

Reorder the terms:
15d + -1d + -5d2 + 2d2 = 0

Combine like terms: 15d + -1d = 14d
14d + -5d2 + 2d2 = 0

Combine like terms: -5d2 + 2d2 = -3d2
14d + -3d2 = 0

Solving
14d + -3d2 = 0
