x^2 - 1 | x^45 | x^43 +x^41 +x^39 .............+x
|x^45 -x^43 (on substracting)
| x^43
| x^43 - x^41 (on substracting)
| x^41
| x^41 - x^39 (on substracting)
| x^39
and so on

| x^3
| x^3 - x (on substracting)
| x
so remainder is x

agrawal: your answer is right and the method is also right but the method is too long and now i know the accurate method to solve it. if you want i will show you.
