Answer 1

Long division...
Do you know how?

Answer 2

(x 3 + 43 - 49x - 7x 2) ÷ (x 2 - 49)

Answer 3

One at a time plz ;)

First write it this way:

3f-4 / 6f² - 11f -13 \

Now with what would you have to multiply 3f to get 6f²? It's 2f.
Multiply 2f with 3f-4, put it below the rest. Subtract and pull in -13:

3f-4 / 6f² - 11f -13 \ 2f
6f² - 8f
------- -
-3f - 13

Same again: multiply with -1:

3f-4 / 6f² - 11f -13 \ 2f - 1
6f² - 8f
------- -
-3f - 13
-3f + 4
-------- -
-17

Remainder is -17, so: \[(6f ^2 - 13 - 11f) ÷ (3f - 4)=2f-1 - \frac{ 17 }{ 3f-4 }\]
