This is a 5 problem set rich in learning. The five problems solved in this video are of different types and includes two difficult and a few tricky ones. All are solved though in mind in minimum time using concepts and techniques such as, pattern discovery, prime number concepts, comparison of coefficients of like terms, golden strategy of algebraic simplification, two methods of double square root surd simplification, pattern discovery, inversion technique, dummy variable substitution, and mathematical reasoning. The Concepts and Techniques, explained with precision and details, form the BASIC SKILLSET for solving harder algebra problems EASILY IN MIND...
