What is the roll-off rate of voltage gain vs frequency of a second order low pass filter?

What is the roll-off rate of voltage gain vs frequency of a second order low pass filter? Correct Answer -12dB/octave

The frequency response of the second-order low pass filter is identical to that of the first-order type except that the stop band roll-off will be twice the first-order filters at 40 dB/decade (12 dB/octave). 

The response of the second order filter is:
