3x+2) 3x^4+5x^3-x^2+13x+9 (x^3 +x^2-x
3x^4+2x^3 +5
=================
3x^3-x^2
3x^3+2x^2
================
-3x^2+13x
- 3x^2-2x
===================
15x +9
15x +10
====================
-1

hence when divide then x^3+x^2-x+5
and remains -1

mysticd: plz , edit abhi from third step to ending

abhi178: now I think right

mysticd: remainder is -1, and quotient = x^3+x^2-x+5

abhi178: yes I got it

mysticd: first step is also wrong why did u write 19/3

abhi178: I correct my step now

abhi178: please tell me

abhi178: sir I think now I'm right

mysticd: one more mistake is there in quotient +5 place should be changed

mysticd: do u understand abhi
