Hey!
Hope this helps...

Please at the attached document for all the work...
Unfortunately, you cannot get any where past (5x^2 + 18) / 6x
If any of the steps look wrong, please let me know ASAP so that I can fix it...
The only thing that would work, is if you substituted 0 for x, you would get 18/0 which is impossible...
OR
If you were to substitute 1 for x, you would get:
= [ 5(1)^2 + 18 ] / 6(1)
= (5 + 18) / 6
= 23 / 6
