$6 + 2 x^{2} - 3 y^{2} - 7 - 2 - 4 x^{2} + 4 y^{2}$

Step 1

Subtract $7$ from $6$ .

$2 x^{2} - 3 y^{2} - 1 - 2 - 4 x^{2} + 4 y^{2}$

Step 2

Subtract $4 x^{2}$ from $2 x^{2}$ .

$- 2 x^{2} - 3 y^{2} - 1 - 2 + 4 y^{2}$

Step 3

Add $- 3 y^{2}$ and $4 y^{2}$ .

$- 2 x^{2} + y^{2} - 1 - 2$

Step 4

Subtract $2$ from $- 1$ .

$- 2 x^{2} + y^{2} - 3$
