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.

Re-writing in Latex to try to understand it better:

$$({2 \frac{1/t}{(1/t)^2 + t}}) ( \frac{-1}{t^2} + 2 \sqrt{\frac{t}{(1/t)^2 + t}} ) (\frac{1}{2 \sqrt{t}})$$

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...

((2/t)/((1/t^2)+t)) (-1/t^2 ) + ((2sqrtt) / ((1/t)^2)+t)) ( 1/2sqrtt)
