God I f*ckin hate math

I have these polynomials:
(8y^2-14y-15) (3y^2-7y-6)
------------------ *-------------
(6y^2-11y-10) (4y^2-9y-9)

Factored:
(-2y+5)(-4y-3) (-3y-2)(-y+3)
------------------*---------------
(3y+2)(2y-5) (4y+3)(y-3)

Now...I need to simplify it down.
So my question is:
Can I cancel out the (3y+2) and the (-3y-2) since the "-" changes the signs? Same for the other ones that change signs?
If that's right...doesnt everything cancel out???

factor -1 out of (-3y-2) and you get (3y+2) it cancels that out then you can do the same for all of them and it'd factor to 1 i believe....
