    make 3 columns

    A -- B ---C
    try
    1 1 1---- 1^2 + 1^2 + 1^2 = 3
    have a list of perfect squares handy :
    1 4 9 16 25 ... 225

    is 3 in the list? NO
    1 1 2 --- 6 , is 6 in the list ? NO
    1 1 3 --- 11 , is 11 in the list ? NO
    ...
    1 1 9 ---83, is 83 in the list ? NO

    1 2 1 ---- already done
    1 2 2 --- 9, is 9 in the list ? YEAHHHH
    1 2 3 ---- 14 NO
    1 2 4 --- 21 NO
    etc

    rather tedious, but do you get the idea?
    there are many duplications
    e.g. 4 3 2 came up in 2 3 4

    Can someone check my answer please! I'm not sure this is right x(squared)+7x+10=0 (x+r)(x+s) =x(squared)+sx+rx+rs =x(squared)+(r+s)x+rs x(squared)+(r+s)x+rs=x(squared)+7x+10 r+s=7 rs=10 (2)(5)=10 and 3+4=7 x(squared)+7x+10=(x+5)(x+2)
