anonymous · Answer

sure what do you think you should do first

anonymous · Answer

$$\frac{3x+12}{8m}*\frac{m^2}{2x+8}$$

anonymous · Answer

cross multiply?

anonymous · Answer

i'm sorry i forgot about you haha, how about we factor first ... what can you pull out of the x functions?

anonymous · Answer

lets say f(x)=3x+12 and g(x)=2x+8

the both have a Common factor

anonymous · Answer

f(x)=?(x+4)    g(x)=?(x+4)

anonymous · Answer

Okay
