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
