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
