(9d-2)(d-1)=0

Solution for (9d-2)(d-1)=0 equation:

Simplifying
(9d + -2)(d + -1) = 0

Reorder the terms:
(-2 + 9d)(d + -1) = 0

Reorder the terms:
(-2 + 9d)(-1 + d) = 0

Multiply (-2 + 9d) * (-1 + d)
(-2(-1 + d) + 9d * (-1 + d)) = 0
((-1 * -2 + d * -2) + 9d * (-1 + d)) = 0
((2 + -2d) + 9d * (-1 + d)) = 0
(2 + -2d + (-1 * 9d + d * 9d)) = 0
(2 + -2d + (-9d + 9d2)) = 0

Combine like terms: -2d + -9d = -11d
(2 + -11d + 9d2) = 0

Solving
2 + -11d + 9d2 = 0

Solving for variable 'd'.
