Describe a disadvantage of using the acronym FOIL.
it might detract you from understanding WHY you do first outside inside last
It can only be used on certain equations that have variable/numbers with numbers on the outside of itself
its rather useless clutter devised as a means of trying to remember how to multiply; but if you cant remember stuff, then trying to remember something to help you remember is rather pointlesss
@amistre64 Thus the disadvantage should be that both the one who uses the acronym and the instructor will be immediately struck by lightening?
the disadvantage is when people get stuck on method, and loose focus on math. FOIL does not teach a person a mathing skill. Multiplication does (or more succinctly, distribution). FOIL is a method to keep track of what you have already multiplied relating to 2 binomials and is not applicable to other polynomials ....
