(a−b)(a(2)+ab+b(2))
=(a+−b)(a(2)+ab+b(2))
=(a)(a(2))+(a)(ab)+(a)(b(2))+(−b)(a(2))+(−b)(ab)+(−b)(b(2))
=2a2+a2b+2ab−2ab−ab2−2b2
=a2b−ab2+2a2−2b2

Answer:
![y = \frac{10x - 1}{45} \\](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B10x%20-%201%7D%7B45%7D%20%20%5C%5C%20)
Step-by-step explanation:
![\frac{10x - 1}{3y} = 15 \\ 10x - 1 = 15 \times 3y \\ 10x - 1 = 45y \\ \frac{10x - 1}{45} = y \\](https://tex.z-dn.net/?f=%20%5Cfrac%7B10x%20-%201%7D%7B3y%7D%20%20%3D%2015%20%5C%5C%2010x%20-%201%20%3D%2015%20%5Ctimes%203y%20%5C%5C%2010x%20-%201%20%3D%2045y%20%5C%5C%20%20%5Cfrac%7B10x%20-%201%7D%7B45%7D%20%20%3D%20y%20%5C%5C%20)
