Find the rational zeros and then the other zeros of the polynomial function f(x) = 2x³ + 5x² +50x + 125, that is, solve f(x) = 0. (b) Factor f(x) into linear factors. (a) Select the correct choice below and fill in any answer box(es) within your choice. (Type an exact answer, using radicals and i as needed. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) OA. There are only rational zeros and they are O B. There is only one rational zero, and the other zeros are +5 i OC. There are no rational zeros. The other zeros are (b) The factorization of f(x) into linear factors is (? )(x-5i)(x+5i)
