Heya !!!

P(X) = 3X⁴ + 5X³ - 7X² + 2X +2

G(X) = ( X² + 3X +1)

On dividing P(X) by G(X) we get,

-------------3X² -4X +2
***********_________________
X²+3X+1 )3X⁴+5X³-7X² +2X+2(

-----------------3X⁴ + 9X³ + 3X²

*******_____- ____- ___-__________

---------------0------- -4X³ -10X² + 2X +2

------------------------- -4X³ -12X² -4X

**********________+___+____+______

-------------------------0-----2X² +6X +2

-------------------------------+2X² +6X +2

********____________-____-___-____
-----------------------------------0---------------

Hence,

Remainder = 0

And,

Quotient = 3X² -4X +2

HOPE IT WILL HELP YOU....... :-)
