List all possible rational zeros. f(x)=7x^3+52x^2+22x+7


To list all possible rational zeros of the polynomial \( f(x) = 7x^3 + 52x^2 + 22x + 7 \), we use the **Rational Root Theorem**. 

The Rational Root Theorem states that any possible rational zero of a polynomial is of the form:

\[
\frac{p}{q}
\]

Where:
- \( p \) is a factor of the constant term (in this case, 7), and
- \( q \) is a factor of the leading coefficient (in this case, 7).

### Step 1: Factors of the constant term (7)
The factors of 7 are:
\[
p = \pm 1, \pm 7
\]

### Step 2: Factors of the leading coefficient (7)
The factors of 7 are:
\[
q = \pm 1, \pm 7
\]

### Step 3: Form all possible values of \( \frac{p}{q} \)
We now list all possible combinations of \( \frac{p}{q} \):

\[
\frac{p}{q} = \pm 1, \pm 7, \pm \frac{1}{7}, \pm \frac{7}{7}
\]

Simplifying:

\[
\pm 1, \pm 7, \pm \frac{1}{7}
\]

### Conclusion
The possible rational zeros of the polynomial \( f(x) = 7x^3 + 52x^2 + 22x + 7 \) are:

\[
\boxed{\pm 1, \pm 7, \pm \frac{1}{7}}
\]
