# How do you find all the zeros of #x^5-2x^4-4x^3-10x^2-21x-12#?

##### 1 Answer

#### Explanation:

The polynomial has constant coefficient

Trying the sequence of

we get

then at last we have found two roots ( keep in mind that some of this roots can be multiple). So we can write

and also

Taking the coefficients equal to zero we have

Solving for

Focusing now in the roots of

and having in mind the ideas about the composition of the constant term we find that

proceeding as before we find
