I have a few problems which are really confusing me, if someone can do one of these out for me, i'd appriciate it.

Code:
y^2-9         8
-------    X  -----
   4             y+3


s^2 + 2s - 8            s+5
----------------   X   -----------
s^2 +3s -10           s^2-16



5m                25m^2
-------     /    ------------
m+1             m^2 + 2m +1

thanks,

Dimava
