1. The problem statement, all variables and given/known data
2(1/t)/(1/t)^2+t * 1/t^2 + 2sqrtt/ (1/t)^2+t * 1/2sqrtt 2. Relevant equations 3. The attempt at a solution my solution = 4t^3 + 3t^2+ 2t/t+ t^4 but incorrect

Okay, well, show us the steps you took to get to your solution? First try canceling out any common factors in the numerators and denominators, I can see a few.

[tex]({2 \frac{1/t}{(1/t)^2 + t}}) ( \frac{1}{t^2} + 2 \sqrt{\frac{t}{(1/t)^2 + t}} ) (\frac{1}{2 \sqrt{t}})[/tex] Did I guess right at your problem statement? If not, use my Latex as a starting point in a QUOTE reply, and fix it up. Then we can talk about your answer...

some algebra simplification
((2/t)/((1/t^2)+t)) (1/t^2 ) + ((2sqrtt) / ((1/t)^2)+t)) ( 1/2sqrtt)

1 Which post are you responding to? Mine or Gib Z's? 2 What are you showing us, the problem simplified, your attempt at a solution, or the solution? 3 Why are you still not using Latex to post your math question? Do what I suggested and use Latex. Just use the QUOTE reply feature to get the simple Latex source for my response, and use that to post your math question. I'd like to welcome you to the PF, but you're making it kind of hard....
