FOIL is an ancronym to help you remember to multiply each term. basically it's for people who can't distribute good

FOIL stands tells you which terms to mulitply, you then add the results up

F=First terms

O=Outer terms
I=Inner terms

L=Last terms



so

(x-2)(x-3)

First: x times x = [tex]x^2[/tex]

Outer: x times -3=-3x

Inner: -2 times x=-2x

Last: -2 times -3=6


now add them all up

[tex]x^2-3x-2x+6=x^2-5x+6[/tex]



answer is the second option
