Answer:

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

Step-by-step explanation:

When multiplying fractions you just go straight accross

this means that our fraction is equal to

((x+2)(3x))/((x-4)(x+4))

The numerator is quite easy 3x(x+2)=3x^2+6x

The second one is a little tough at first and if you need help I would reccomend using khan academy

but pretty much you get x^2-16

put them together and get your answer
