How do you get the same denominator between two fractions?

anonymous · Answer

These are my choices   

6x2 + 8x + 4

 6x2 + 4x – 4

 6x2 + 9x + 4

 6x2 + 9x – 4

To combine these, what is your first step? $$\frac{2}{x} + \frac{2}{x - 1} + \frac{2}{x + 2}$$

I'm confused by your drawing from my understanding the denominator was already in the problem. It just didn't change... Clearly I messed up lol.
