![\huge\boxed{\boxed{2z-12}}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ky0y4ct53iir4tew4oiyph9pomh8bnujbf.png)
Explanation:
Hello.
Please remember that the Distributive Property states that
a(b+c)=ab+ac
Where
a, b, and c can be constants or variables.
In this case, it's flopped over:
(c+b)a=ca+ba
Use the second formula:
(z-6)2=2z-12
And we're done!
I hope it helps & have an outstanding day!
