Explanation Formula Used: ( 1 ) Division Algorithm: If f ( x ) and g ( x ) are polynomials in F [ x ] , with f ( x ) a nonzero polynomial. There exist unique elements q ( x ) and r ( x ) in F [ x ] such that g ( x ) = f ( x ) q ( x ) + r ( x ) with either r ( x ) = 0 or deg r ( x ) < deg f ( x ) . The polynomial q ( x ) is called the quotient and r ( x ) is called the remainder in the division of g ( x ) by f ( x ) . The Euclidean Algorithm consists of repeated application of division algorithm to yield the following sequence, where r n ( x ) is the last nonzero remainder. Euclidean Algorithm: 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 n − 2 ( x ) = r n − 1 ( x ) q n − 1 ( x ) + r n ( x ) deg r n ( x ) < deg r n − 1 ( x ) r n − 2 ( x ) = r n ( x ) q n ( x ) Suppose that a is the leading coefficient of the last nonzero remainder, r n ( x ) .Then a − 1 r n ( x ) is the greatest common divisor of f ( x ) and g ( x ) . ( 2 ) If f ( x ) = a x j + … , g ( x ) = c x k + … with a ≠ 0 , c ≠ 0 , and j ≤ k , then a x j + … c a − 1 x k − j c x k + … c a − 1 x k − j f ( x ) _ g ( x ) − c a − 1 x k − j f ( x ) Explanation: Consider the provided functions. f ( x ) = x 3 + 2 x 2 + 2 and g ( x ) = 2 x 5 + 2 x 4 + x 2 + 2 Here a = 1 , c = 2 , j = 3 and k = 5 . Divide g ( x ) by f ( x )
