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....... :-)
