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

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

Langkah 1

Terapkan sifat distributif.

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

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

Langkah 2

Kalikan

- 8

$- 8$ dengan

9

$9$ .

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

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

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

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