This is the question i'm stuck on:
aaa Rewrite this expression without absolute value signs, treating various cases separately where necessary.
aaa
When a is negative (ie. a=k);
kkk
k2k
k2k=3k=3a
When a is positive (ie.a=k)
kkk
kkk
k0=k=a
So when a is negative the expression is just 3a.
When a is positive the expression is a.
I just wanted to know if that's correct. The question before it was a lot more complicated, this one seems too easy to be true.....

Have some confidence, yes its correct.

Thanks again Bobak.
I've been doing so much stuff wrong lately that it's making me freak out (and not in the good way!).
I'll be better in a few days or so.
