Question

aum · Answer

Do the long division:
                           
                           5a^2 - 6a
                        -----------------------------
5a^2 + 6a - 9  |  25a^4 +   0a^3 +19a^2 - a - 78
                           25a^4 + 30a^3
                          ------------------------
                                      - 30a^3 + 19a^2
                                       -30a^3 - 36a^2
                                     -------------------

what is the rest

aum · Answer

I showed you the first two steps of doing the long division.  You have to complete the rest of the steps.  If you are not familiar, type polynomial long division in YouTube and watch a couple of videos to learn.  It is a bit difficult to explain long division here by typing.

aum...???

i think the divison will not end...

aum · Answer

Once you get to the last term and if it does not divide evenly you express the result as quotient + remainder / divisor.
