H.C.F. of the polynomials \( \Large x^{2}+3x+2 \) and \( \Large x^{3}+3x^{2}+3x+1 \) using Euclidean algorithm is
Correct Answer: Description for Correct answer:
\( \Large x^{2}+3x+2 = \left(x+1\right) \left(x+2\right) \)
\( \Large x^{3}+3x^{2}+3x+1 = x^{3}+x^{2}+2x^{2}+2x+x+1 \)
= \( \Large x^{2} \left(x+1\right)+2x \left(x+1\right)+1 \left(x+1\right) \)
= \( \Large \left(x+1\right) \left(x^{2}+2x+1\right) \)
Therefore, \( \Large HCF = x+1 \)
