How many roots does the polynomial (x^3-3x+1)^2

There are no solutions to the polynomial.

Explanation:

First of all, you can cancel out the constant  

3

which will get you  

x

2

+

x

+

1

. After this, to check for how many roots this has, we can use the discriminant  

b

2

−

4

a

c

. If this value is  

0

, then the polynomial has  

1

solution. If the value is positive, the polynomial has  

2

solutions. If the value is negative, than the polynomial has no solutions. In this case, we have  

1

2

−

4

(

1

)

(

1

)

=

−

4

=

−

3

Because our result is negative, there are no solutions to this polynomial.
