Hey guys, math newbie here. I've run into a bit of a hazzle, trying to simplify this equation:

I honestly have no clue where to begin. My first intuition, was to simplify the brackets one at the time: (6x-5)(2x+7) and then multiply that result with the next bracket and so on, until

finally multiplying it all with 2 and leaving the denominator intact, but I realize that I'm completely off.

If someone could show me the first step or point me in the right direction, I'd be very happy.

Thank you!
