Answer:
The given polynomial can have at most 8 roots.
Explanation:
Here, the given polynomial is
![f (x) = x^(8) + 2x^(5) -3x + 4](https://img.qammunity.org/2020/formulas/mathematics/high-school/r12xhsg1imq14vujcsy9voibewyoh5f52j.png)
Now, by FUNDAMENTAL THEOREM OF ALGEBRA:
A polynomial of degree n can have at most n distinct real roots.
Here, the given polynomial is of degree 8. ( highest power of x)
So, by the stated theorem can have at most 8 roots which might or might not be distinct in nature.
