SUMMARY

The remainder when dividing the polynomial expression (x^3 + 1) by (x^2 + 3) is -3x + 1. This conclusion is reached after performing polynomial long division, where the divisor (x^2 + 3) has a higher degree than the remainder (-3x + 1). The discussion emphasizes that the remainder must always have a lower degree than the divisor, confirming the result is valid.

(x^3 +1)/(x^2 +3) = ?


_X______
X^2 + 3 / X^3 +1
- X^3 +3X
-----------
-3X +1
From here. I cannot figure out what to do.

Hint: your work is done. :wink:
 
Second hint: the remainder, -3x+ 1 has lower degree than the divisor.

8/3= 2 with remainder 2 or 2+ 2/3, because the remainder, 2, is less than the divisor, 3.
