    Do I start by using the FOIL method? (4x-3y) (4x-3y)

    Okay. Thank you for your help. It's been a long time since I've used the FOIL method. I'm working on solving it...slowly but surely. I'll let you know if I come up with the same answer as yours.

    I just learned this if you still need help I can, but I don't use the foil method I don't think

    Use Square of Difference: (a−b)2=a2−2ab+b2 (4x)2−2×4x×3y+(3y)2

    Use Distributive Property (Multiplication): (xy)a=xaya 42x2−2×4x×3y+(3y)2

    yeah you can distribute if you change the problem to (4x - 3y)(4x - 3y)

    @Buster14 You forgot the O and the I in FOIL

    @Pax Snap...the O is very important. I will work it again.

    @Buster14 And the I too, but since it is a perfect square binomial the O and the I should be the same

    @Thesmarterone I will try your method as well. Can't go wrong when using a calculator. @KaylaIsBae I'm working on your way too. Thank you all so much! I have a huge test tomorrow!

    (a - b)^2 = a^2 - 2ab - b^2 I believe that is what I used in my school lesson

    @KaylaIsBae , the formula is (a - b )^2 = a^2 - 2ab + b^2 :)

    @KaylaIsBae Nursing, I'm taking the TEAS test tomorrow. Thanks for the visual formula, so helpful. I understand it now!
