13b^2-13

I got

(13b-13)(1b-1).

On my test my teacher said it was party wrong.And she underlined the two Thirteen's i had in my answer.

And i dont understand why!?

_______________________________________

Also on another one.The problem is..

2d^2+3d-2

I got

(2d+2)(1d+1)

But she crossed out the numbers two and one, on my paper.And i dont understand Why?

Please if you could HELP ME!

i would be very greatful!

thanx

Factor completely means complete. You can factor 13 out...

13(b-1)(b+1)

if you multiply out what you put in parenthisis, it wont be equal to the original. Notice the - sign on the last term.

Try

(2d-1)(d+2)

what is any number to a negative power equal to?
