FOIL stands for "First, Outer, Inner, Last."
"First" refers to the first term of each factor: here, this would be x and x
"Outer" refers to the outermost terms of each factor: here this would be x and 3
"Inner" refers to the innermost terms of each factor (those nearest the middle): here this would be -2 and x
"Last" refers to the last term of each factor: here this would be -2 and 3
Utilizing the foil method, one adds together the indicated products (so the product of the First terms, plus the product of the Outer terms, etc.)
F: xx=x2
O: x*3=3x
I: -2*x=-2x
L: -2*3=-6
Adding these together yields
x2+3x2x6=x2+x6
