How do you use the FOIL method if there is only one set of parenthesis...
Because you use distributive property with 2 sets

Algebra 2 
Reiny,
The FOIL "method" refers specifically to the multiplication of two binomials
e.g. (2x+3)(4x1)
F : first times first  8x^2
O : the outsiders  2x
I : insiders  12x
L : the lasts  3
when you have a monomial times a binomial
e.g.
3x(2x+5y)
just use the distributive property
= 6x^2 + 15xy
in effect you are using the distributive property when you are doing the FOIL thing
(2x+3)(4x1)
= 2x(4x  1) + 3(4x  1)
= 8x^2  2x + 12x  3
= ...
