which part u didn't get ?
for limit to be continuous, u need to have lim x>0 ... = lim x>0+ ..

why at 0?

because the point of discontinuity can be 0 only... as the function behaves differently (different definition) before and after 0

because of the domain restrictions?

u can say that, but mostly its because of t<=0 ..... t> 0
if it were
t<=2..... t>2, then u would have checked at x=2

okay... how does a=b?

because , for continuity , lim x>0 needs to be equal to x>0+
and lim x>0 was 1
so, x> 0+ = a/b = 1
