The cube of binomial (x+y) is the sum of four terms where each term can be  obtained as follows.
    First term: the cube of x
    Second term: three times the product of X2(x squared) and y
    Third term: three times the product of x and y2
    Fourth term: cube of y

for all x and y, (x+y)3 = x3 +3x2y+3xy2+y3        
                      (x-y)3= x3-3x2y+3xy2-y3

pasensya na di ma superscript ung 3 kaya medyo magulo...
