(a + b)2 = a2 + 2ab + b2  3.a2 + b2 = (a + b)2 – 2ab  (a – b)2 = a2 – 2ab + b2  (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca  (a – b – c)2 = a2 + b2 + c2 – 2ab + 2bc – 2ca  (a + b)3 = a3 + 3a2b + 3ab2 + b3 ; (a + b)3 = a3 + b3 + 3ab(a + b)  (a – b)3 = a3 – 3a2b + 3ab2 – b3 = a3 – b3 – 3ab(a – b)  a3 – b3 = (a – b)(a2 + ab + b2)  a3 + b3 = (a + b)(a2 – ab + b2)  (a + b)4 = a4 + 4a3b + 6a2b2 + 4ab3 + b4  (a – b)4 = a4 – 4a3b + 6a2b2 – 4ab3 + b4  a4 – b4 = (a – b)(a + b)(a2 + b2)  a5 – b5 = (a – b)(a4 + a3b + a2b2 + ab3 + b4)  (a +b+ c)2=a2+b2+c2+2ab+2bc+2ca
