*(a+b)2 = a2+b2+2ab
*(a+b)2 = (a-b)2+4ab
*(a-b)2 = (a+b)2-4ab
*(a-b)2 = a2+b2-2ab
*a2 –b2 = (a+b)(a-b)
*a2+b2 = (a+b)(a+b)
*a2+b2 = (a-b)2+2ab
*a3+b3 = (a+b)(a2+b2+ab)
*a3+b3 = (a+b)3+3ab(a+b)
*a3+b3 = (a+b)(a2+b2-ab)
*a3+b3 = (a+b)3+3ab(a-b)
*a3-b3 = (a+b)(a2+b2+ab)
*a3-b3 = (a-b)3+3ab(a-b)
*2(a2+b2) = (a+b)2+(a-b)2
*4ab = (a+b)2+(a-b)2
*A4+b4 = (a+b)(a-b)[(a+b)2-2ab)]
*A4+b4 = [(a+b)2-2ab]2 -2(ab)2
*(a+b+c)2 = a2+b2+c2+2ab+2bc+2ca
*(a+b-c)2 = a2+b2+c2+2ab-2bc-2ca
*(a-b-c)2 = a2+b2+c2-2ab+2bc-2ca
*(a+b)3 = a3+b3+3a2b+3ab2
*(a-b)3 = a3-b3-3a2b+3ab2
