$27 x^{2} - 5 y^{2} + (12 y^{2} - 14 x^{2})$

Step 1

Remove parentheses.

$27 x^{2} - 5 y^{2} + 12 y^{2} - 14 x^{2}$

Step 2

Subtract $14 x^{2}$ from $27 x^{2}$ .

$13 x^{2} - 5 y^{2} + 12 y^{2}$

Step 3

Add $- 5 y^{2}$ and $12 y^{2}$ .

$13 x^{2} + 7 y^{2}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
