Question 168528
We need to simplify this equation 
3a^2-9a-12/6a^2+30a+24 
--------------
Divide by 3 and factor out 2 in the DEN.  That makes it easier to factor further.
{{{(a^2-3a-4)/2(a^2+5a+4)}}}
={{{(a-4)*(a+1)/(2*(a+4)*(a+1))}}}
={{{(a-4)/(2(a+4))}}}
It is simpler.
BTW, it's not an equation, it's an expression.  An equation will have an equal sign, something equals something else.
