I wouldn't factor out -a, I would just factor out a.
factoring out a, you get, a(a-1)
factoring out -a, you get, -a(-a+1)

u are wrong, trust me on this one!
a^2-a= a(a-1)
first u need to find the LCF(least common factor) of a^2-a. notice how the "a" is the only "common" and the "least". so place the "a" outside the parenthesis and the remainders factors inside.
a(a-1) multiplied out will give u a^2-a. [a(a)=a^2 and a(-1)=-a]
im 1000% positive im right! i should be chosen as best answer;)
