Answer:
Given :
→x-y=12
→xy= 3²
=9
Equation formed:
![{(x - y)}^{2} = {x}^{2} + {y}^{2} - 2xy](https://tex.z-dn.net/?f=%20%7B%28x%20-%20y%29%7D%5E%7B2%7D%20%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%20%20%7By%7D%5E%7B2%7D%20%20-%202xy)
Step by step explanation:
![{(12)}^{2} = {x}^{2} + {y}^{2} - 2 \times 9 \\ 144 + 18 = {x}^{2} + {y}^{2} \\ = 162](https://tex.z-dn.net/?f=%20%7B%2812%29%7D%5E%7B2%7D%20%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%20%20%7By%7D%5E%7B2%7D%20%20-%202%20%5Ctimes%209%20%5C%5C%20%20144%20%20%20%2B%2018%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%20%20%7By%7D%5E%7B2%7D%20%20%5C%5C%20%20%3D%20162)

Answer: 28-6x
This is the same as -6x+28
===============================
To get that answer, you multiply each term inside the parenthesis by the outer term 2
14 * 2 = 28
-3x * 2 = -6x
So,
(14-3x)*2 = 14*2 - 3x*2 = 28-6x
----------
The distribution rule says
a(b-c) = ab-ac
which is the same as saying
(b-c)a = ba-ca
We can flip things around because we can multiply in any order.
