Question 78335
<pre>
Please help me solve this:
{{{(3x^2+9x-30)/(3x^2-75)}}}


     3x^2 + 9x - 30
   _________________
       3x^2 - 75


Factor out the common factor 3 each term both numerator and denominator

   3(x^2 + 3x - 10)
 ___________________
    3 (x^2 - 25)


     3(x+5)(x-2)
  ________________
    3(x+5)(x-5)


     {{{cross (3(x+5))}}}(x-2)
  ________________
    {{{cross (3(x+5))}}}(x-5)


           x - 2 
         __________
           x - 5
