just substitute a instead of x
that's after substitute
I need to find the lim x>a (as "x" approaches "a") of
ax^2 - 2x^2 + a - a^2x + 2a^2 - x
(x - 2)(a - 2)(x - a)
I factored out (x - a) and got
ax - 2x - 2a -1
(x - 2)(a - 2)
I think I am on the right track but don't know where to go from here.
Thanks for any help.
