Am not that great in math.

Question

Describe the different methods that can be used to find the product:
(2x-5)(3x-1). I know there is the foil method.

Describe the different methods that can be used to find the product:
(5x+1)^2

Answer 1

you can line it up just like normal arithmetic multiplication

2x-5
3x-1
------
......... -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

Answer 2

Yeah I would just use the FOIL method because its way easier...
