Options

  1. A0
  2. B1 2 2
  3. C1 4 2
  4. D1 2

Correct answer

A. 0

Step-by-step solution

aligned & _ x 0 x^3 ( x^2+ x^4+1 - 2 x ) &= _ x 0 ( x^2+ x^4+1 + 2 x . ( x^2+ x^4+1 + 2 x . & x^3 ( x^2+ x^4+1 - 2 x ) &= _ x 0 (x^3 ) ( x^4+1 -x^2 ) & _ x 0 1 x^2+ x^4+1 + 2 x &= _ x 0 (x^3 ) ( x^4+1 -x^2 ) ( x^4+1 +x^2 . x^4+1 +x^2 &= _ x 0 x^3 x^4+1 +x^2 =0 aligned
