Answer:
f(x) = (x-2) (x+10)
Step-by-step explanation:
f(x)=x^2+8x-20
Factor the right hand side
What 2 numbers multiply to -20 and add to 8
-2 * 10 = -20
-2 + 10 = 8
Then we can use the zero product property to help us to find the zero's
B.f(x)=(x+6)(x-2)
apexs
9.00$
6 divided by 2 = 3 so each pakage cost 3$ so it would be 9.00$
