Answer:
14x + x^2
------------------
9x^2
Step-by-step explanation:
2x /x^2 + (x-4)/ 9x
Cancel the common factor of x in the first term
2 /x + (x-4)/ 9x
We need a common denominator of 9x
2 /x *9/9 + (x-4)/ 9x
18/9x + (x-4)/9x
Add the numerators
18+x-4
--------------
9x
14+x
----------
9x
Multiply the top and bottom by x to get it to match one of the answers
14x + x^2
------------------
9x^2
