lim x --> 0

(1/2+x) - (1/2)

_____________

x

. . . I know the answer's -1/4, I just don't know how to get there.

I'm not really even sure why it's confusing me. I just got done with a chapter about limits... Maybe the x's in both numerator and denominator are killing me..?

I know I can't substitute. Gwah!
