i got this question but not sure what to do

Write down an expression of the form

____K__+___K^2___
ax+b.......cx+d
thats k over ax+b + k^2 over cx+b

where a and c are non zero and the denominators are distinct.

I know i have to replace a,b,c,d and x with numbers but do i do em all at once or seperate and what about k, please help

In the absence of any other instruction - I would put numbers for all the constants including "k". Yes you would do those all at once.

for example

3/(5x + 7) + 3[sup:3gyc7y5q]2[/sup:3gyc7y5q]/(2x + 1)[/spoiler:3gyc7y5q]
 
ok i put a=2 b=0 c=3 d=1 k=4 x=5
and i got
__4__+__16__
2(5)+0 3(5)+1

_4_+_16_
10 ... 16
=1 4/10
do you think thats the answer to the original question??
