3. Question:

Which of the following is the GCD of the polynomials x^3+x^2+x+1 and x^4-1? Indicate all such statements.

  • A. (x+1)(x^2+1)
  • B. (1+x^2)(1+x)
  • C. (1+x)(x^2-1)
  • D. x(x+2)
  • E. (x+1)(x^2+2)

[x^2=x*x]

Correct Answer: A and B

Explanation:

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

=(x^2+1)(x+1)

x^4-1=(x^2+1)(x^2-1)

=(x^2+1)(x+1)(x-1)

GCD = (x^2+1)(x+1)

The options A and B are true.
