Question 75833
<pre>
         2x^2 – x -3         3x^2 – 11x – 20 
       _______________  *   _________________    
        3x^2 + 7x + 4           4x^2 - 9


FActor both numerators and denominators

       (2x - 3)(x + 1)         (3x + 4)(x - 5)
       ________________   *   ___________________
       (3x + 4)(x + 1)         (2x - 3)(2x + 3)



Divide the greatest common factors

       {{{cross ((2x - 3)(x + 1))}}}         {{{cross(3x + 4)}}}(x - 5)
       ________________   *   _________________
       {{{cross ((3x + 4)(x + 1))}}}         {{{cross(2x - 3)}}}(2x + 3)




         x - 5
       _________
