(a – b)2 = a2 – 2ab + b2
a2–b2 = (a – b)(a + b)
a2 + b2 = (a – b)2 + 2ab
(a + b)3 = a3 + 3a2b + 3ab2 + b3
(a + b)3 = a3 + b3 + 3ab(a + b)
(a – b)3 = a3 – 3a2b + 3ab2 – b3
a3 – b3 = (a – b)(a2 + ab + b2)
a3 + b3 = (a + b)(a2 – ab + b2)
(a + b)3 = a3 + 3a2b + 3ab2 + b3
(a – b)3 = a3 – 3a2b + 3ab2 – b3
(a – b – c)2 = a2 + b2 + c2 – 2ab – 2ac + 2bc
(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)
(x + a)(x + b) = x² + (a + b)x + ab
(x - a)(x - b) = x² - (a - b)x + ab
(x + a)(x + b)(x - c) = x³ - (a + b + c)x² (ab + bc + ca)x - abc
a³ + b³ + c³ - 3abc = (a + b + c)(a² + b² + c² - ab - bc - ca)
