(Q10) Check in which case the first polynomial is a factor of the second polynomial by dividing the second polynomial by the first polynomial x3-3x+1, x5-4x3+x2+3x+1

Answer

Given first polynomial x3-3x+1,

Second polynomial x5-4x3+x2+3x+1

Let us divide x5-4x3+x2+3x+1

by x3-3x+1, we get

2-

x3-3x+1) 5-x3+2+x+
5-x3+2
-    +   -

-3+x+
-3+x-
+    -   +

+

Here remainder is (≠0)

Therefore x3-3x+1 is not a factor of x5-4x3+x2+3x+1
