Answer:
The zeros are (-5,-4,-1)
Step-by-step explanation:
Since we have a linear factor, we can use the method of long division to get the other factors
What this mean is that we simply divide the polynomial by the linear expression
we have this division result as;
By dividing, we have the other factor as ;
x^2 + 3x - 4
so we simply factorize this
x^2 -x + 4x - 4
x(x-1) + 4(x-1)
(x + 4)(x-1)
So the complete factors are;
(x + 5)(x + 4)(x-1)
To get the zeros, we simply equate each of the terms to zero
and we have our answer as;
-5 , -4 , 1
