step by step pls ​

Answer 1

Step-by-step explanation:

( a+ (-b) +c)²

a² + b² + c² - 2abc

(2x-2y+2z)²

4x²+4y²+4z²- 16xyz

Answer 2

Step-by-step explanation:

using identity (x+y+z)^2=x^2+y^2+z^2+2xy+2yz+2zx

solution

(2x)^2+(2y)^2+(2z)^2+2(2x)(-2y)+2(-2y)(2z)+2(2z)(2x)

=4x^2+4y^2+4z^2-8xy-8yz+8zx. answer
