English: So I should have $\frac{d}{dx}\left( \frac{y_{1}}{y_{2}} \right) = \left\lbrack 0\ 1\ - \frac{a_{2}}{a_{0}}\ - \frac{a_{1}}{a_{0}}\ \right\rbrack\left( \frac{y_{1}}{y_{2}} \right) + \left( \frac{0}{\frac{f(x)}{a_{0}(x)}} \right)$.
Telugu: కాబట్టి నాకు $\frac{d}{dx}\ఎడమ( \frac{y_{1}}{y_{2}} \కుడి) = \ఎడమ\lbrack 0\ 1\ - \frac{a_{2}}{a_{0}}\ - \frac{a_{1}}{a_{0}}\ \కుడి\rbrack\లెఫ్ట్(\frac{y_{1}}{y_{2}} \కుడి) + \లెఫ్ట్(\frac{0}{frac{f(x)}{a_{0}(x)}} \కుడి)$.
