Question

(4x-3y)^2 simplify

Answer 1

16x²+9y²-24xy I think

Answer 2

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

Answer 3

That's what I did @Buster14

Answer 4

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.

Answer 5

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

Answer 6

I got a different answer: 16x^2 + 9y^2

Answer 7

let me see what I got

Answer 8

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

Answer 9

That's what that is called ^

Answer 10

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

Answer 11

Simplify 42 to 16
16x2−2×4x×3y+(3y)2

Answer 12

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

Answer 13

@Buster14 You forgot the O and the I in FOIL

Answer 14

Use Distributive Property (Multiplication): (xy)a=xaya
16x2−2×4x×3y+32y2

Answer 15

Simplify 32 to 9
16x2−2×4x×3y+9y2

Answer 16

Simplify 2×4x×3y to 24xy
16x2−24xy+9y2

Done :D

Answer 17

live help not a calculator lolol plus kinda confusing to read

Answer 18

I am a calculator :)

Answer 19

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

Answer 20

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

Answer 21

@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!

Answer 22

okay you're welcome :)

Answer 23

@Thesmarterone I think your way is confusing...2 many steps!

Answer 24

(a - b)^2 = a^2 - 2ab - b^2

I believe that is what I used in my school lesson

Answer 25

Well, after all, it is the hard way :L
