Step-by-step explanation:
To find the real zeros you must match the function to zero and factor the expression.
We have a polynomial of degree 3.
We try to group the terms to perform the factorization

Now we take (x + 4) as a common factor

If we have an expression of the form
we know that this expression is equivalent to:

In this case

So:

Finally:

The solutions are:
