# Question #733f9

##### 1 Answer

There is no third degree linear equation.

Three degree polynomial equations with at least one rational root(s) can be solved by factorization. See below.

#### Explanation:

A

If you mean third degree

with a form

[Example] Solve

[Step 1] Find a rational zero on the equation. This step needs some perseverance.

If a third degree polynimial

they must be

In this example, divisors of

Therefore the rational "canditates" for the equation are

Let

and you will find

This means that

[Step2] Factor the polynomial using the result of [Step 1].

In this case,
