Explanation Given Information: Euclidean Algorithm: f ( x ) and g ( x ) are nonzero polynomials in F . g ( x ) = f ( x ) q 0 ( x ) + r 1 ( x ) deg r 1 ( x ) < deg f ( x ) f ( x ) = r 1 ( x ) q 1 ( x ) + r 2 ( x ) deg r 2 ( x ) < deg r 1 ( x ) r 1 ( x ) = r 2 ( x ) q 2 ( x ) + r 3 ( x ) deg r 3 ( x ) < deg r 2 ( x ) ⋮ ⋮ r j − 3 ( x ) = r j − 2 ( x ) q j − 2 ( x ) + r j − 1 ( x ) deg r j − 1 ( x ) < deg r j − 2 ( x ) r j − 2 ( x ) = r j − 1 ( x ) q j − 1 ( x ) + r j ( x ) deg r j ( x ) < deg r j − 2 ( x ) Proof: f ( x ) and g ( x ) are two nonzero polynomials in F . g ( x ) = f ( x ) q 0 ( x ) + r 1 ( x ) deg r 1 ( x ) < deg f ( x ) f ( x ) = r 1 ( x ) q 1 ( x ) + r 2 ( x ) deg r 2 ( x ) < deg r 1 ( x ) r 1 ( x ) = r 2 ( x ) q 2 ( x ) + r 3 ( x ) deg r 3 ( x )
