Answer 5

When you find zeros, for the first one, it means set x=0 and simplify. So do that to the first one and tell me what you get

Answer 6

c? x=9? or x=-9

Answer 7

Wait, nvm, I think it's just asking to factor the top.. so if that's right:
x(4x-36)=0
x=0
4x-36=0
-------------------
x=36/4=9
------------------
So x=0, and 9

Answer 8

okay #2

Answer 9

Just factor the top, and what do you get?

Answer 10

(x+4)(x-7)

Answer 11

x+4 can cel and im left with x-7

Answer 12

Correct, so there's a hole at x=4
(4, y)
To find what y is, plug 4 back into x-7

Answer 13

-3 c

Answer 14

Correct

Answer 15

#3

Answer 16

Factor first

Answer 17

Answer 18

Correct, and we have a hole, can you identify where it's at?

Answer 19

isk :(

Answer 20

Well, we know it's at x=4, and both C and D have the same (4, 5) meaning it's that, now we just need to find zeros. So solve for x at 2x-3=0.

Answer 21

how do i solve 2x-3=0 like this?
