\large \left( 7rs + 3r^{2}s- 3s\right) \cdot \left( r^{2}s- 2\right)
\large = 3{r^{4}}{s^{2}} + 7{r^{3}}{s^{2}} - 3{r^{2}}{s^{2}} - 6{r^{2}}s- 14rs + 12s
\large = 3{r^{4}}{s^{2}} + 7{r^{3}}{s^{2}} + 3{r^{2}}{s^{2}} - 6{r^{2}}s- 14rs + 6s
\large = 3{r^{4}}{s^{2}} + 7{r^{3}}{s^{2}} - 3{r^{2}}{s^{2}} - 6{r^{2}}s- 14rs + 6s
\large = 3{r^{4}}{s^{2}} + 7{r^{3}}{s^{2}} - 3{r^{2}}{s^{2}} - 6{r^{2}}s- 14rs - 6s
