JEE Main 7 April 2025, Shift 1, Maths Q20

Question 20 of 75 in this shift, Maths question 20 of 25, Section A.

Let y=y(x)y = y(x) be the solution curve of the differential equation x(x2+ex) dy+(ex(x−2)y−x3) dx=0x(x^2 + e^x)\,dy + (e^x(x-2)y - x^3)\,dx = 0, x>0x > 0, passing through the point (1,0)(1, 0). Then y(2)y(2) is equal to
  1. (1)44−e2\frac{4}{4-e^2}
