Answer:

k

Step-by-step explanation:

Answer 2

Answer:

$2(m {}^{2} - n {}^{2} + 2) - 6(m {}^{2} - 4n { }^{2} + 1) + 2( - 3m { }^{2} + 2n {}^{2} - 2) \\ = 2m {}^{2} - 2n {}^{2} + 4 - 6m {}^{2} + 24n {}^{2} - 6 - 6m {}^{2} + 4n {}^{2} - 4 \\ = 2m {}^{2} - 6m {}^{2} - 6m {}^{2} - 2n {}^{2} + 24n {}^{2} + 4n {}^{2} + 4 - 6 - 4 \\ 10m {}^{2} + 26n {}^{2} - 6$

Step-by-step explanation:

Answer = 10m^2 + 26n^2 - 6
