Let A and B be two n × n matrices. The result: (a−b) 2 = a 2 − 2ab + b 2. Since both terms are perfect cubes, factor using the sum of cubes formula, a3 +b3 = (a+b)(a2 −ab+b2) a 3 + b 3 = ( a + b) ( a 2 - a b + b 2) where a = a a = a and b = b b = b. you can also check cube formula in algebra formula sheet.
