I have a bunch of questons but I don't know if I use FOIL in them and how to sepearte them for BEDMASS and stuff. :/
Here is an example of one:
(X+5)(X+4)+4(2X-2)²-(3X-4)(3X+4)
Please if you can help me with this one then I am sure I can manage through the rest. Thanks guys!
Well, in the states, students learn expansion of two terms by the FOIL acronym. First, outside, inside, last.
F, stands for first, or the 1st variables/numbers of which are x and x
O, stands for outside, or the two variables/numbers on the outside, or x and 4.
I, stands for inside, or the insides... 5 and x
L, stands for last, or the last (2nd) variables/numbers of the product of terms
Sum them up for the result:
