Multiplication And Division Of Algebraic Fraction

                    Lesson 1

                                                                                                                                                                          

                                                            Problem:                   Multiply: 9x2/x-4 x2-16/18

                                                            Solution                    Rewrite: = 9x2/x-4 (x+4)(x-4)/18

                           Step 1:  

                     

                                                                                Solution                          9 cancels 9 and 18

Step 2:                        

 

                                                                                Solution                           Cancel (x-4) with (x-4) = x2(x+4)/2

Step 3:           

             

                                                            Solution                    The answer is:  x2(x+4)/2

 Step 3:                                                                      

 Complete                                                                   

                                                                                                                               

                                                             Try two practice problems:  

Solve:

 

A. 4x2/(x-2)(x2-4)/12

 

B. 7x2/(2x-8)(x2-16)/14
