LESSON 6: RATIONAL EXPRESSIONS PART 2

 

Multiplying Rational Expressions:

Text Box: Multiplying Rational Expressions:
	Factor the numerators and denominators of all expressions if possible
	Reduce to lowest terms by dividing out common factors
	Write answer as a single rational expression
	State any restrictions  remember the denominators cannot equal 0.
 

 

 

 

 

 

 

 

 


Example 1:

a) b) c)

Solution:

a) ** Multiply (numerator x numerator) and (denominator x denominator)

** Reduce to lowest terms

** State restrictions

 

 

b) ** Factor numerator and denominator

** Divide out common factors

** State restrictions

 

c)

 

 

Dividing Rational Expressions:

 

 

Text Box: Dividing Rational Expressions:
	Factor the numerators and denominators of all expressions if possible
	Multiply by the reciprocal of the second expression
	Reduce to lowest terms by dividing out common factors
	Write answer as a single rational expression
	State any restrictions  remember the denominator cannot equal zero in the first expression and neither the numerator nor the denominator can equal zero in the second expression.
