Extending Differentiation (Question)

A curve has equation y=(x2+1)4+2(x2+1)3. Show that dy/dx=4x(x2+1)2 (2x2+5) and hence show that the curve has one stationary (critical) point. State the coordinates of the stationary point and, by considering the gradient of the curve on either side of the stationary point, determine its nature.
