CHAPTER 5 : RATIONAL ALGEBRAIC EXPRESSIONS
5.1 Definitions
Any algebraic expression, that is a quotient of two other algebraic expressions, is called a rational algebraic expression. Thus if P and Q are algebraic expressions and Q ¹ 0 then
the expression is called a rational algebraic expression.
We say that a rational algebraic expression is meaningless for those values of the variable for which the denominator Q is zero.
To simplify rational algebraic expressions, we may be required to factorize algebraic expressions in the numerator and /or denominator.
Operations with algebraic fractions (i.e. rational algebraic expressions)
