If a curve passes through the point1, -2and has slope of the tangent at any pointx, yon it asx2-2yx, then the curve also passes through the point

Options:

Answer:
A
Solution:

dydx=x2-2yx

dydx+2xy=x.  It is in linear form.

I.F.=e2xdx=e2lnx=x2

y.x2=x.x2 dx=x44+c

At x=1, y=-2,

-2×12=144+c

c=-2-14=-94

curve is y.x2=x44-94

It passes through 3, 0.
