(3n - 2m)^2 \\ \\ (3n)^2 - 2 \times 3n \times 2m + (2m)^2 \\ \\ 3^2n^2 - 2 \times 3n \times 2m + (2m)^2 \\ \\ 9n^2 - 2 \times 3n \times 2m + (2m)^2 \\ \\ 9n^2 - 2 \times 3n \times 2m + 2^2m^2 \\ \\ 9n^2 - 2 \times 3n \times 2m + 4m^2 \\ \\ 9n^2 - 12mn + 4m^2
The final result would be, 9n² - 12mn + 4m².
Answer: It is correctly simplified form.
Step-by-step explanation:
Since we have given that
[tex]-3m-[2x+(5-m)]+7[/tex]
We need to simplify the above expression:
[tex]-3m-2m-5+m+7\\\\=-5m+m+2(\text{gather the like terms})\\\\=-4m+2\\\\=2-4m[/tex]
So, [tex]-3m-[2x+(5-m)]+7=2-4m[/tex]
Hence, it is correctly simplified form.
