Given differential equation is dxdy=2(xy2−x2)y3 By substituting z=y2, we get diff. eqn. as dxdz=2(xz−x2)2z2=xz−x2z2 Now, dzdx=zx−z2x2=zx[1−zx]≈F(zx) Hence, statement-1 is true. Now, y2e−y2/x=C satisfies the given diff. equation ∴ It is the solution of given diff. equation. Thus, statement −2 is also true.
Consider the differential equation : d y d x= y^3 2 (x y^2-x^2 ) Statement-1: The substitution z=y^2 transforms the above equation into a first order…
