9 (x^{2} + x y - 8 y^{2})

$9 (x^{2} + x y - 8 y^{2})$

Step 1

Apply the distributive property.

9 x^{2} + 9 (x y) + 9 (- 8 y^{2})

$9 x^{2} + 9 (x y) + 9 (- 8 y^{2})$

Step 2

Multiply

- 8

$- 8$ by

9

$9$ .

9 x^{2} + 9 x y - 72 y^{2}

$9 x^{2} + 9 x y - 72 y^{2}$

⎡ ⎢ ⎣ \begin{matrix} x^{2} & \frac{1}{2} \sqrt{π} & \int x d x \end{matrix} ⎤ ⎥ ⎦

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