Question

(m²+mn+n²)(m²-mn+n²)​

Answer 1

To be real I don’t know I don’t understand math with all those letters

Answer 2

Answer:

$m^{4\\}$+$m^{2}$$n^{2}$+$n^{4}$

Step-by-step explanation:

If you're distributing each value, I would recommend you to use the lattice method so that you can work on it faster.  Make sure to add the exponents instead of multiplying to have an accurate answer.  Once your done then cross out the ones that would subtract to 0 which would leave you with $m^{4\\}$+$m^{2}$$n^{2}$+$n^{4}$ as your final answer if you did it properly.
