Using the Rational Zeros Theorem (\(\frac{p}{q}\) where p is the factors of the constant, and q is the factors of the Leading Coefficient) List all possible rational zeros for the given function. Then, algebraically determine which, if any, possible zeros are actually zeros.

f(x)=2x3-9x2+14x-5

 

I've done the Rational Zeros Theorem, and can confidently say that 1/2 is the only zero in that list that works.

x =  1/2 is the only real root
