Answer 2

Ok, let me try that

Answer 3

post what you get

Answer 4

Ok, I got, x=(6/5) x=-(7/2) AND x=4

Answer 5

excellent

Answer 6

Ok, now what?

Answer 7

thats it, those are the zeros of that function

Answer 8

What happened to the -3 though?

Answer 9

what happens when you set -3 to be zero

Answer 10

there is no x to solve for

Answer 11

So the -3 means nothing?

Answer 12

Answer 19

what did you get koolkimberly?
