    YOu need to FOIL\[(3m^3-\frac{ 1 }{ 2 }y)(3m^3-\frac{ 1 }{ 2 }y)\]Plain-vanilla FOIL goes like this:\[(a+b)(c+d)=ac(F)+ad(O)+bc(I)+bd(L)\]so try to do that with your numbers:\[F: 3m^3 \cdot 3m^3=...\]\[O:3m^3 \cdot -\frac{ 1 }{ 2 }y=...\]\[I:-\frac{ 1 }{ 2 }y \cdot 3m^3=...\]\[L:-\frac{ 1 }{ 2 }y \cdot -\frac{ 1 }{ 2 }y=...\]Then try piecieng the bits together where possible!

    Maybe this also helps: F =First - multiply the first number in the left pair of ( ) with the first one in the right O = Outer I = Inner L = Last

    What I showed WAS FOIL. The student just simply does not get it and spends more time complaining rather than trying to understand.
