Question 971897
 I messed up and made my 1st question non-understandable. My sincerest apologies. please Let me try again. I am having an issue with this problem. I am subtracting rational expressions with the same denominators. Here is the problem:

(x-6)(x+3)/X^2-2x-15 minus 9(x-5)/x^2-2x-15

I have figured out that the denominator should be (x-5)(x+3) but I am having trouble with the numerator. could you help me?<pre>{{{((x - 6)(x + 3)/(x^2 - 2x - 15)) - 9(x - 5)/(x^2 - 2x - 15)}}}
{{{((x - 6)(x + 3) - 9(x - 5))/(x^2 - 2x - 15)}}} 
{{{(x^2 - 3x - 18 - 9x + 45)/(x^2 - 2x - 15)}}} ----- Distributing terms in numerator
{{{highlight_green((x^2 - 12x + 27)/(x^2 - 2x - 15))}}} ---------- Combining like-terms
That's your answer!!
