What are the zeros of the polynomial function? f(x)=x^2+9x+20
the zeros of f(x)are ___ and ___

-4 and -5

Step-by-step explanation:

factor the polynomial

x^2+9x+20

(x+5)(x+4)

set factored expression to zero to get answer

0=(x+5)(x+4)

x=-5 and -4

i think it is 70

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
