rational expressions

If you take the 2 out of 4y+2 to get 2(2y+1) then use that 2 to multiply with the 7y^2 to get 14y^2 then that cancels out with the 14y^2 on the bottom and your left with what o_O said

edit: and put your brackets correctly. i guess most people assume you meant
(7y^2 / (y^2 - 9)) * ((4y + 2) / 14y^2)

But sometimes that wont be so obvious
