Question 90970: I have two problems I'm trying to get done. I can't get anywhere with them. Can I please get some assistance.
Find each of the following squares.
(7p + 6q)^2
(w - 1/4)^2
Thank you for helping me out. I'm totally lost.

Find the squares:
%287p%2B6q%29%5E2 Rewrite this as:
%287p%2B6q%29%287p%2B6q%29 Now use the FOIL method to multiply the terms in this order:
F...First. %287p%29%287p%29+=+49p%5E2
O...Outer. %287p%29%286q%29+=+42pq
I...Inner. %286q%29%287p%29+=+42pq
L...Last. %286q%29%286q%29+=+36q%5E2 now put them all together to get:
%287p%2B6q%29%5E2+=+49p%5E2%2B84pq%2B36q%5E2
