\frac{3y\left(y-3\right)}{6\left(y-3\right)\left(y+8\right)y^{2}}+\frac{\left(y-5\right)\times 6\left(y+8\right)}{6\left(y-3\right)\left(y+8\right)y^{2}}

Untuk menambahkan atau mengurangi ekspresi, perluas untuk menyamakan penyebutnya. Kelipatan persekutuan terkecil dari 6y\left(y+8\right) dan y^{2}\left(y-3\right) adalah 6\left(y-3\right)\left(y+8\right)y^{2}. Kalikan \frac{3}{6y\left(y+8\right)} kali \frac{y\left(y-3\right)}{y\left(y-3\right)}. Kalikan \frac{y-5}{y^{2}\left(y-3\right)} kali \frac{6\left(y+8\right)}{6\left(y+8\right)}.

\frac{3y\left(y-3\right)+\left(y-5\right)\times 6\left(y+8\right)}{6\left(y-3\right)\left(y+8\right)y^{2}}

Karena \frac{3y\left(y-3\right)}{6\left(y-3\right)\left(y+8\right)y^{2}} dan \frac{\left(y-5\right)\times 6\left(y+8\right)}{6\left(y-3\right)\left(y+8\right)y^{2}} memiliki penyebut yang sama, tambahkan bilangan dengan menambahkan pembilangnya.

\frac{3y^{2}-9y+6y^{2}+48y-30y-240}{6\left(y-3\right)\left(y+8\right)y^{2}}

Kalikan bilangan berikut 3y\left(y-3\right)+\left(y-5\right)\times 6\left(y+8\right).

\frac{9y^{2}+9y-240}{6\left(y-3\right)\left(y+8\right)y^{2}}

Gabungkan seperti suku di 3y^{2}-9y+6y^{2}+48y-30y-240.

\frac{9y^{2}+9y-240}{6y^{4}+30y^{3}-144y^{2}}

Luaskan 6\left(y-3\right)\left(y+8\right)y^{2}.
