Answer 3

FOIL method
Multiply the (F)first terms.
In this case the two "2x"s

add them with the product of the (O) outer terms
In this case -3 and +3

add them with the product of the (I) inner terms
In this case -3 and the second 2x

Finally, add them with the product of the (L) last terms
In this case -3 and 3

The FOIL method :D

Answer 4

Oops! The (O) outer terms are the first 2x and 3. Sorry!
