As posted, the expression appears to be:

. . . . . $\frac{3}{a^2}\, +\, (a)\times(2a)\, +\, \frac{2}{6}$

Was this what you meant? Also, what were the instructions?

Thank you!

Perform the indicated operation

3 is over a squared +a x 2a+2 over 6

Still a little vague. As written you could mean:

$\frac{3}{a^2} + (a)\left(\frac{2a+2}{6}\right)$

or
$\frac{3}{a^2+a}\left(\frac{2a+2}{6}\right)$

or what Stapel_eliz wrote or three or four other possibilities (English is tricky, ain't it?).

So, use grouping symbols like parentheses: "3 is over (a squared + a)" and such. Help us see what the entire numerators and denominators are.

answere is a^4 + a^3 + 9 all divided by 3a^2. if you want to see every step, go to www.wolfram.com and type in the information and it will show you every step.

The answer is as listed if a particular one of the earlier guesses as to meaning was correct. If that particular guess was incorrect, then "the answer" is something else.

Unfortunately, we'll never know for sure until the original poster provides the necessary clarification....
