Check whether 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
Check whether the first polynomial is a factor of the second polynomial by applying the division algorithm:
g(x) = x3 – 3x + 1, f(x) = x5 – 4x3 + x2 + 3x + 1

उत्तर
x3 – 3x + 1, x5 – 4x3 + x2 + 3x + 1
x2 – 1
`x^3 - 3x + 1")"overline(x^5 - 4x^3 + x^2 + 3x + 1)`
x5 – 3x3 + x2
– + –
–x3 + 3x + 1
–x3 + 3x – 1
+ – +
2
Since the remainder ≠ 0.
Hence x3 – 3x + 1 is not a factor of x5 – 4x3 + x2 + 3x + 1.
