someone help
posted by erin .
my post is still on this page as algebra, could someone elaborate on what bobpursley tried to help me with.
See your original post.
I am guessing you are referring to your question
5)Simplify:(5x4)^2
and your answer= 25x^2  16
(5x4)^2
=(5x4)(5x4)
= 25x^2  20x  20x + 16
= 25x^2  40x + 16
The FOIL that bobpurseley was referring to means
F  multiply the firsts
O  multiply the outside terms
I  multiply the inside terms
L  multiply multiply the last terms
it is a short memoryaid to help you multiply two binomials
