Am not that great in math.
Describe the different methods that can be used to find the product:
(2x5)(3x1). I know there is the foil method.
Describe the different methods that can be used to find the product:
(5x+1)^2

you can line it up just like normal arithmetic multiplication
2x5
3x1

......... 2x + 5
6x^2 15x
_______________
6x^2  17x + 5
(hoping that the x terms line up vertically)
best way to do (5x+1)^2 is using FOIL in
(5x+1)(5x+1)
= 25x^2 + 5x + 5x + 1
= 25x^2 + 10x + 1 
Yeah I would just use the FOIL method because its way easier...
