Are you trying to simplify this expression? If so, you need to cancel common factors in the numerator and the denominator. For example, there is a y in both so you cancel it out. However there may be another common factor...but to find it, you will have to factorise the quadratic term in the denominator.

4y(y-3)(y+4)/y(y^2-y-6)Cancel y on top and bottom:4(y-3)(y+4)/(y^2-y-6)Lets factorise y^2- y - 6(y-3)(y+2)So now we have:4(y-3)(y+4)/(y-3)(y+2)We can now cancel (y-3) on top and bottom to leave us with:4(y+4)/(y+2)

Assuming simplification is what you are after then follow this:
