Answer:

\dfrac{c}{3(c+2)}

Step-by-step explanation:

\dfrac{c^2+4c}{c^2-4} \div \dfrac{3c+12}{c-2}=\dfrac{c^2+4c}{c^2-4} \times  \dfrac{c-2}{3c+12}=\dfrac{(c^2+4c)(c-2)}{(c^2-4)(3c+12)}

Factor c^2-4:    c^2-4=(c-2)(c+2)

\implies\dfrac{(c^2+4c)(c-2)}{(c+2)(c-2)(3c+12)}

Cancel the common factor  (c-2):

\implies\dfrac{(c^2+4c)}{(c+2)(3c+12)}

Factor  c^2+4c:  c^2+4c=c(c+4)

Factor  3c+12:  3c+12=3(c+4)

\implies\dfrac{c(c+4)}{3(c+2)(c+4)}

Cancel the common factor  (c+4):

\implies\dfrac{c}{3(c+2)}
