8.1 Addition and Subtraction of Algebraic Expressions In earlier classes, we have already become familiar with what algebraic expressions (or simply expressions) are. Examples of expressions are: x + 3, 2y – 5, 3x2, 4xy + 7 etc. In the earlier classes, we have also learnt how to add and subtract algebraic expressions.

• Representation of an algebraic expression as the product of two or more expressions is called factorisation. Each such expression is called a factor of the given algebraic expression. • When we factorise an expression, we write it as a product of its factors. These factors may be numbers, algebraic (or literal) variables or algebraic ...
The limit laws allow us to evaluate limits of functions without having to go through step-by-step processes each time. For polynomials and rational functions, \[\lim_{x→a}f(x)=f(a). \nonumber \] You can evaluate the limit of a function by factoring and canceling, by multiplying by a conjugate, or by simplifying a complex fraction.
