$4 z^{2} - 5 z y - 2 y^{2} + (- 6 z^{2} - 3 z y - 3 y^{2})$

Step 1

Remove parentheses.

$4 z^{2} - 5 z y - 2 y^{2} - 6 z^{2} - 3 z y - 3 y^{2}$

Step 2

Subtract $6 z^{2}$ from $4 z^{2}$ .

$- 2 z^{2} - 5 z y - 2 y^{2} - 3 z y - 3 y^{2}$

Step 3

Subtract $3 z y$ from $- 5 z y$ .

$- 2 z^{2} - 2 y^{2} - 8 z y - 3 y^{2}$

Step 4

Subtract $3 y^{2}$ from $- 2 y^{2}$ .

$- 2 z^{2} - 5 y^{2} - 8 z y$

Step 5

Reorder.
