Answer:

$\large\boxed{Zeroes: 5\:and\:-4}$

Explanation:

How to find the zeros of an equation?

To find the zeros of an equation, you'll need to factor it first.

To factor the expression
f(x)=x^(2) -x-20} , you'll need to think of two numbers
and
such that:

$\begin{cases} xy=-20\\x+y=-1 \end{cases}$

The numbers are
and
. So, these are the zeros of the function
f(x)=x^(2) -x-20 .
