# Is this boolean expression reducible?

I have this boolean expression: F1 = a1'a2' + a1a2'.

Could it be reduced even more?

Yes. If you can't just see it, write out a logic table and see what you get. –  The Photon Dec 22 '12 at 18:55

Yes, factor out the a2'. You should see something interesting with what happens to a1.
