1.
Start with the given expression
When you FOIL, you multiply the terms in this order:
F-First (i.e. you multiply the first terms in each parenthesis which in this case are and )
O-Outer (i.e. you multiply the outer terms in each parenthesis which in this case are and )
I-Inner (i.e. you multiply the inner terms in each parenthesis which in this case are and )
L-Last (i.e. you multiply the last terms in each parenthesis which in this case are and )
So lets multiply the first terms:
multiply and to get
So lets multiply the outer terms:
multiply and to get
So lets multiply the inner terms:
multiply and to get
So lets multiply the last terms:
multiply and to get
Now lets put everything together
So the expression
FOILs to:
