Please provide Handwritten answer

Precalculus

A.) Use the Rational Zeros Theorem to list all possible zero(s) of the function f(x)=x^3+5x^23x+10

B.) Use the Rational Zeros Theorem to list all possible zero(s) of the function f(x)=3x^3+2x^2+x+7 (You do not need to factor the polynomial)

(Can someone answer this as soon as possible please??)
