For the differential equation $\frac{dy}{dx} + xe^{y}+2x=0$ It is given that $y=0$ when $x=0$. When $x=1$, $\:y$ is given by $\text{ln} \bigg(\frac{3}{2e} – \frac{1}{2} \bigg)$ $\text{ln} \bigg(\frac{3e}{2} – \frac{1}{4} \bigg)$ $\text{ln} \bigg(\frac{3}{e} – \frac{1}{2} \bigg)$ $\text{ln} \bigg(\frac{3}{2e} – \frac{1}{4} \bigg)$

#Last month preparation advice
Is it OK to be nervous during this period? Didn’t posted anything other than question on GO. But today I am feeling very low because of anxiety. Same happened with me in 2018 despite of good preparation. Some motivation is welcomed. :)
