bleh I gave up math

Since when?
I want to give up math too but can't... at least a couple more months to go for me (if not taking Math 12)

Stupid question, but 呢題點做?

If f(x) = x - 5 and g(x) = x^2 - 3 determine:
f(x^2 - 2) - g(x - 5)

It's supposed to be really easy but I totally forgot how to do it when I got home after class...
