1. factor everything. 2. cancel common factors

No kidding?

3. BTaylor

seriously. usually you get a nice answer.

They didn't take the answer I had. I know *how* to solve it -___- I just missed something, somwhere.

5. BTaylor

what were your factors?

(3a-1)(a-4)/(3a-1) • 7(4+a)/(a-4)(a+4)

Oh gosh. @bhaweshwebmaster Thank you so much! I screwed up really bad after cancelling out factors. Oops. o.o

10. BTaylor

you just forgot that it was (3a-1)^2, right?

Lol I'm not exactly sure what I did but I came up with 3(2a-1)/2 O.O

Lol I'm a fail.

Quite Easily Done

its Latin for something that means "I did it!"

Oh! Thanks, guys! :)

18. bhaweshwebmaster

Quod erat Demonstrandum it is.

QED means "It is Finished"
