hi everyone here is the quiz question find the general solution of the given differential equation
2y'' -3y' +y = 0
therefore 2r^2 -3r + 1 = 0
therefore (2r-1)(r-1) = 0
R1 = 1/2 R2 = 1
therefore y = C1e^((1/2)t)+C2e^t

Find the general solution of the given equation:
xy' = (1-y^2)^1/2
solution: Because Separable,
therefore x(dy/dx) = (1-y^2)^1/2,
Rearrange: \int(1/(1-y^2)^1/2)*dy =\int(1/x)dx, where x not equal 0, y does not equal to positive or negative 1,
therefore: arcsin(y) = ln|x| + C,
therefore general solution: y=sin(ln|x| + C) where x not equal to 0, y not equal to positive 1 or negative 1.
