IMPORTANT FORMULAE FOR COMPETITIVE EXAMS. Important formulae used in simplification: (a + b)2 = a2 + b2 + 2ab. (a – b)2 = a2 + b2 – 2ab. (a + b)2 = (a – b)2 + 4ab. a2 – b2 = (a – b) (a + b) a3 + b3 = (a + b) (a2 – ab + b2) a3 – b3 = (a – b) (a2 + ab + b2) 1. 2 [(a 2 b) (a. �. 2. Rules of counting numbers. n. numbers. n n 1 . = 2.
