1)
5 - h -18 = 25

2)
- 15 + 18_ z = - 23

3)
27 + r 2 = - 3

4)
26 + n -10 = 18

5)
19 - b 15 = - 17

6)
f - 15 -9 = - 13

7)
v + 13 -11 = - 20

8)
- 16 - 8d = 10

9)
x - 2 19 = 21

1 2 3 4 5 6 7 8 9 the answer is 5

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn
