Answer 3

yes

Answer 4

Ok. Now first let's do something that you make think is unrelated but isn't really. So hang with me.

Answer 5

Can you factor x^2-x-6 ?

Answer 6

not really
(x-3)(x+2)?

Answer 7

Oh good. I see that you can factor it.

Answer 8

thats correct?

Answer 9

Yes it is correct. See, you're smarter than you thought, aren't you?

So if I wrote (x-3)(x+2)=0 could you solve that?

Answer 10

x=-3,x=2?

Answer 11

Almost. Remember: if you multiply numbers and get 0 then one of the numbers have to be zero. Do you know that?

Answer 12

i didn't so it would be 0,6?

Answer 13

-6**

Answer 14

Hold it.
(___)(6)(5)(-3)(4)=0 What goes in the blank?

Answer 15

....? i really dont know

Answer 16

Let's make it shorter. ( ) times 4 = 0. What is the blank?
