I am not sure on how to aimplify algebraic expressions. They have this process called FOIL. first, outer, inner and then last.  Could u please explain to me a little more in depth how this works. Looking at their examples just confuses me... here is one- (2x-3)(x+3)= 2x cubed + 3x - 9... where did the 9 come from? Its all about \"polynomials\"   hope u can help me! Thank you.      Jesyka </SPAN>\n" );
