Answer 6

I get you, same here.
But first what you do is find common factors, what numbers do you know, when multiplied equal 27?

Answer 7

4 and 9 and 1

Answer 8

Actually it would be 3 and 9
and 27 and 1

Answer 9

right sorry

Answer 10

Since the 27 in the equation is negative, it means that one of the numbers is negative and the other is positive

Answer 11

could we do 3*(-9)

Answer 12

and the +6w is saying that when it is foiled out the positive number should be bigger then the negative one

and yes we could

Answer 13

but watch out, does (x-9)(x+3) give you a positive 6?

Answer 14

no the 3 would have to be the negative right?

Answer 15

Yup :)

Answer 16

so then it would be (x-3)(x+9) right?

Answer 17

Yes

Answer 18

The only real challenging part is finding factors and where the pos.and neg. signs go
