The sum of the order and degree of the differential equation: (x+dydx)2=dydx+1\left(x + \frac{dy}{dx}\right)^2 = \frac{dy}{dx} + 1 is

Solution

✅ Correct Option: 2

Expanding gives x2+2xdydx+(dydx)2=dydx+1x^2 + 2x\frac{dy}{dx} + \left(\frac{dy}{dx}\right)^2 = \frac{dy}{dx} + 1. The highest derivative is the first, so order 1, and its highest power is 2, so degree 2. The sum is 3.
