Learn how to do the box method for factorization of a quadratic polynomial. Understand the steps to be followed with a proper explanation along...
The article focuses on completing the square with the use of TI-Nspire computer algebra system (CAS). It states that CAS automatically generates family members of squares for a specified trinomial p(x). It discusses the calculation of algebraic expressions in square completers using the CAS-...
Both complexes 1a and 1b are paramagnetic, as shown by the paramagnetic NMR spectrum of 1b (Supplementary Fig. 11), and the effective magnetic moment μeff of 3.03 μb determined using the Evans method is consistent with a triplet ground state (S = 1), as expected for a high-spin...
