A square foot is measured 12''x12'' x12''x12'', or a 12'' square.
If you mean: (12x-3)(12x+3) then it is 144x^2 -9
GCF = 12x.24x = 2(12x)36x3 = 3x2(12x)
2*2 - 12x +16 =0 4 - 12x +16 =0 -12x + 16 +4 =0 -12x + 20 =0 -12x = -20 x = 1.666666667
5/4x+7/12x is the same as 15/12x+7/12x = 21/12x

X12. Youtube shows why in a turtle beach video.
