Part 1 of 2 (a) Find the rational zeros and then the other zeros of the polynomial function \( f(x)=x^{3}-91 x+90 \); that is, solve \( f(x)=0 \). (b) into linear factors. (a) Select the correct choice below and fill in any answer box(es) within your choice. (Type integers or fractions. Use a comma to separate answers as needed. Type exact answers, using radicals as needed. Expres B. The rational zero(s) is/are \( \square \), and the other zero(s) is/are C. There are no rational zeros. The other zeros are
