Determine whether the indicated real number is a zero of the given polynomial function f. 1if(x)=x36x2+11x6 Yes, 1 is a zero. No, 1 is not a zero. If yes, find all other zeros. (If no, enter NA. Enter your answers as a comma-separated list.) x= If yes, give the complete factorization of f(x). (If no, enter NA. Do not attempt the factorization of f(x) if the indicated real number is not a zero.) f(x)= Determine whether the indicated real number is a zero of the given polynomial function f. 4;f(x)=x38x211x+148 Yes, 4 is a zero. No, 4 is not a zero. If yes, find all other zeros. (If no, enter NA. Enter your answers as a comma-separated list.) x= If yes, give the complete factorization of f(x). (If no, enter NA. Do not attempt the factorization of f(x) if the indicated real number is not a zero.) f(x)=(x+4)(x214x+50) Use division to show that the indicated polynomial is a factor of the given polynomial function f. (x+5)2;f(x)=x44x362x2+180x+1325 Yes, the indicated polynomial is a factor of the given polynomial function. No, the indicated polynomial is not a factor of the given polynomial function. Find all other zeros. (If there are no other zeros, enter NA. Enter your answers as a comma-separated list.) x= Give the complete factorization of f(x) f(x)=
