[Vergo]

It's an equation and no sorry vergo you not right...since modulus is ALWAYS positive the answer will stay positive. Alloy is right there are two outcomes, but if your doing stationary points, and not modulus equations which are ALWAYS positive. Hence I'm right, sorry guys
EDIT: oh I see what you mean vergo no 3 is actually the answer to number 4 and 4 is 5, I skipped 3 whoops

Sorry man you're wrong it's -3 and it can be negative , also they're not always 2 outcomes
I know what i said cuz i always was good in math :P
