### Random polynomial of degree 1

~~I defined polynomial ring like this. Here is K is ~~Having defined

- the finite field
`K`

of size 4 in ~~'a'~~`a`

- a polynomial ring
`R1`

over `K`

one can ask for a random element using the `random_element`

method.

The random polynomial I obtained that way was of degree two:

~~R1=PolynomialRing(K,['z%s'%p ~~sage: K.<a> = FiniteField(4)
sage: R1 = PolynomialRing(K, ['z%s' % p for p in ~~range(1,3)])
~~

When I call `random_element`

function

```
range(1, 3)])
sage: R1.random_element()
```

I get the following output,

```
(a)*z1*z2 + (a + 1)*z2^2 + z1 + (a)*z2
```

~~But ~~If I only want a random linear polynomial from this ~~ring? How ~~ring, how can I ~~do it? ~~

I would be grateful for the help.get one?
