$(- 4 t^{2} - 9 t v - 16 v^{2}) + (16 t^{2} - 9 t v + 4 v^{2})$

Step 1

Remove parentheses.

$- 4 t^{2} - 9 t v - 16 v^{2} + 16 t^{2} - 9 t v + 4 v^{2}$

Step 2

Add $- 4 t^{2}$ and $16 t^{2}$ .

$12 t^{2} - 9 t v - 16 v^{2} - 9 t v + 4 v^{2}$

Step 3

Subtract $9 t v$ from $- 9 t v$ .

$12 t^{2} - 16 v^{2} - 18 t v + 4 v^{2}$

Step 4

Add $- 16 v^{2}$ and $4 v^{2}$ .

$12 t^{2} - 12 v^{2} - 18 t v$
