MATH 103, COLLEGE ALGEBRA — USEFUL FORMULAS. Review and Chapter 1 — Basic Concepts of Algebra, Functions, Graphs.
Basic Algebra 0.1 The Laws of Algebra Terminology and Notation. In this section we review the notations used in algebra. Some are peculiar to this book. For example the notation A:= B indicates that the equality holds by de nition of the notations involved. Two other notations which will become important when we solve equations are =) and ().
x3 + a3 = (x + a) x2 ax + a2. x3 a3 = (x a) x2 + ax + a2. x2n a2n = (xn an) (xn + an) If n is odd then, xn an = (x a) xn 1 + axn 2. b2 4ac 2a If b2 4ac > 0 – Two real unequal solns. If b2 4ac = 0 – Repeated real solution. If b2 4ac < 0 – Two complex solutions.
