$x{\left( {\frac{{dy}}{{dx}}} \right)^2} - x + a = 0$
B
$\frac{{{d^2}y}}{{d{x^2}}} + xy = 0$
✓
$dy + dx = 0$
D
None of these

✓

Answer

Correct option: C.

$dy + dx = 0$

c
(c) Option $(a)$ First order and second degree.

Option $(b)$ Second order and first degree.

Option $(c)$ First order and first degree.

$i.e.$, $dy + dx = 0$or $\frac{{dy}}{{dx}} + 1 = 0$.
