Simplyfying an equation (low level math)
Hey guys, math newbie here. I've run into a bit of a hazzle, trying to simplify this equation:

Attachment 25735

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!

$\displaystyle \frac{(6x-5)(2x+7) - (3x^2-5x) \cdot 2}{(2x+7)^2}$

$\displaystyle \frac{12x^2 + 32x - 35 - 6x^2 + 10x}{(2x+7)^2}$

$\displaystyle \frac{6x^2 + 42x - 35}{(2x+7)^2}$
