Now, we can use the quadratic formula to find the other 2 zeros.

We know that

a= 2

b= 15

c=7

We have found the three zeros:

(x - 4)

(x + 7)

(x + 1/2)

The Rational Zero Theorem.

You need to list all the possible factors of p (6) and q (4).

Also, all the values of (p/q). [Take into account that there are duplicates, just cross them out]Now, you must use synthetic division with all values of (p/q) in order to determine if they are zeros. For example, I will use synthethic division with (1/3).As you can see, there is no remainder. Therefore, 1/3 is one of the equation's zeros. You do the work for the other ones if you need it.

The three zeros for this equation are:

(x - 1/3)

(x - 1)

(x + 2)
