Question

Good morning all my math wizards:) Can someone tell me if I did this right in finding the product? (xy-5)^2 =(x^2)(y^2)-5^2=xy^4-5^2?

Answer 1

the formula says:
(a-b)^2 = a^2 - 2ab + b^2
so
(xy-5)^2 = (xy)^2 - 10xy +25

Answer 2

Oh man, I was way off. Ok, let me try it. I mean I am sure you are right, just have to do it to make sure I understand what I am doing;) ty sooooooooo much!!! Denise;)

Answer 3

Where does the 10xy come from Hoblos?

Answer 4

look at the formula i gave you....
2ab= 2(xy)(5)=10xy

Answer 5

Ok

Answer 6

I am sorry, I don't think I'm awake enough to be doing this but I will keep looking at the formula;) ty again, Denise:)

Answer 7

my pleasure XD
