Question 288124: When using the FOIL memory device, which letter in FOIL instructs you to multiply the 4 and the 2x in (3x + 4)(2x – 5)?
A. F
B. I

D. O Answer by amnd(23) (Show Source):
You can put this solution on YOUR website! FOIL would stand for:
F = firsts (multiply the first part of the two expressions)
O = outers (multiply the ones on the "outside", i.e. the first and last)
I = inners (the "inside" part; the second and third)
L = lasts (the ones on the end of the two expressions)
(3x +4)(2x-5)
4 and 2x would be the INNERS, which means the solution would be I [B]
