Expanding the expression we get:
(6/u^2 - 9 + 1/3 - u)*u^2 + 6u + 9/5
= (6u/u^2 - 9u + 2/6 - u^3) + 6u + 9/5
= (6/u - 9u + 1/2 - u^3) + 6u + 9/5
= 6/u - 9u + 1/2 - u^3 + 6u + 9/5
= 6/u + 6u - 9u + 1/2 + 9/5 - u^3
= 6/u - 3u + 1/2 + 9/5 - u^3
Therefore, the expanded expression is 6/u - 3u + 1/2 + 9/5 - u^3.
Expanding the expression we get:

= (6u/u^2 - 9u + 2/6 - u^3) + 6u + 9/5
= (6/u - 9u + 1/2 - u^3) + 6u + 9/5
= 6/u - 9u + 1/2 - u^3 + 6u + 9/5
= 6/u + 6u - 9u + 1/2 + 9/5 - u^3
= 6/u - 3u + 1/2 + 9/5 - u^3
Therefore, the expanded expression is 6/u - 3u + 1/2 + 9/5 - u^3.
