Let f(x) and g(x) be polynomíais as shown below. f(x)=a 0 +a 1 x+a 2 x^ 2 ...+a n x^ n s(x)=b 0 +b 1 x+b 2 x^ 2 -+b xy x^ m the following is true about and f(x) * f * (x) f(x) g(x) under subtraction because when subtracted the result will be a polynomial. and A(x) under subtraction because when subtracted the result will be a polynomial. \pi(x) are closed under subtraction decause when subtracted, result be a polynomial. g(x) ) and g(x) are not closed under subtraction because when Subtracted, the will not be a polynomial.
