hELLO Sir...

a3+b3 = (a+b)3-3ab(a+b)   >>>This one is the formula for Expanding only...

a3-b3 = (a-b)3+3ab(a+b)

AND

a3+b3 = (a+b) (a2-ab+b2)  >>>This is the formula for FACTORISING....

a3+b3 = (a-b) (a2+ab+b2)

a3 - b = (a-b) (a 2 +ab+b2)     (multiply these to expression)

  =a3+a2b+ab2-a 2 b+ab2-b3  (+a2b-a 2 b=0  +ab2+ab2= 0  )

  =a3-b3
