Step 1
The Rational Root Theorem states that any rational root, p/q, of a polynomial must be such that p is a factor of the constant term (in this case, 12) and q is a factor of the leading coefficient (in this case, 9). Show more…

Find all zeros of the polynomial function or solve the given polynomial equation. Use the Rational Zero Theorem, Descartes’s Rule of Signs, and possibly the graph of the polynomial function shown by a graphing utility as an aid in obtaining the first zero or the first root. $f(x)=x^{3}+12 x^{2}+21 x+10$

Zeros of Polynomial Functions
In Exercises 39–52, find all zeros of the polynomial function or solve the given polynomial equation. Use the Rational Zero Theorem, Descartes’s Rule of Signs, and possibly the graph of the polynomial function shown by a graphing utility as an aid in obtaining the first zero or the first root. $$ f(x)=x^{3}+12 x^{2}+21 x+10 $$
For the following exercises, use the Rational Zero Theorem to help you solve the polynomial equation. $$4 x^{4}+8 x^{3}+19 x^{2}+32 x+12=0$$
