Oblique asymptotes y= -3x +3

Vertical asymptotes #x=(-3+-sqrt 3)/3#

Explanation:

On division the given expression appears like this

(-3x +3)+ # (16x+3)/(3x^2 +6x +2)#

Oblique asymptote is given by y=-3x+3

Vertical asymptotes are given by #3x^2 +6x+2=0#, that is #x= (-6+- sqrt(36-12))/6#

#x=(-3+-sqrt 3)/3#
