3.3.20 Reduced or special Riccati ode y=axn+by2

3.3.20.1 Reduced Riccati with n=2
3.3.20.2 Reduced Riccati with n2

This is special case of the general Riccati ode y=c0(x)+c1(x)y+c2(x)y2 where now c0(x)=axn and c2(x)=b where a,b,n are constants. The reduced Riccati ode do not have y term in it. Only x and y2 in the RHS of the ode.
