    that's FOIL, right? i think it would be better if you explained what exactly to do rather than giving an equation, but that's just me

    you have to use FOIL. First times First, Outer times Outer, Inner times Inner, and Last times Last

    what's latex? A milky fluid found in many plants, such as poppies and spurges, that exudes when the plant is cut and coagulates on exposure to the air. The latex of the rubber tree is the chief source of natural rubber?
