Find all the zeros of the function

### Question Description

Given a function and one of its zeros find all of the zeros of the function:

2x^3 + 7x^2 - 53x - 28; x - 4

______________________________

Using the rational zero theorem, list all the possible rational zeros for the function:

p(x) = 6x^3 + 4x^2 - 14x + 4  Since the highest exponential degreee of the equation is (3), then the equation has 3 zeros.

We already know one of the zeros: (x-4). Thus, we must divide the equation in order to get  new one. We will divide

(2x^3 + 7x^2 - 53x - 28) / (x-4)    using synthetic division

After divinding, we get a new equation:
2x^2 + 15x + 7
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:

1. (x - 4)
2. (x + 7)
3. (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:

1. (x - 1/3)
2. (x - 1)
3. (x + 2) Cesaraug (72)
