Am not that great in math.

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

  • Algebra Please Help - ,

    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

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