Use the rational root theorem.A. List possible rational Zeros

If x = 2 is a root, then the polynomial is divisible by x - 2 by the polynomial remainder theorem. You can use polynomial long division to find the ratio, which is a quadratic polynomial. Its roots can be found using the quadratic formula.B. find all the zeros (real and complex) of the function (test x=2 as a rational zero using the synthetic division?
