Algebraic expressions involve variables and numbers combined using operations like addition and multiplication. Identities are equations that are always true, no matter the values of the variables, such as a2 - 2ab + b2 = (a - b)2. This document discusses algebraic expressions and identities, which are important concepts in algebra.
