Answer:

- 5

- 3

- 2

Step-by-step explanation:

the factorization of the polynomial is:

[tex]x^5-9x^4+13x^3+57x^2-86x-120=(x-5)(x-4)(x-3)(x+1)(x+2)[/tex]

Hence, we have

- - - - - - - - - - - - - - - - - - - -

The polynomial p(x) = x5 − 9x4 + 13x3 + 57x2 − 86x − 120 has a total of [5}

zeroes. It can have a maximum of

[ 3] positive real roots and a maximum of

[ 2] negative real roots.
