Question 843887
You look for something to factor and might really mean this:  {{{(-a+3)/(-2a-6)}}}, when using the proper grouping symbols and also including the rendering tags.


Factorize everything that can be.
{{{(-a+3)/((-2)(a+3))}}}
Multiply the rational expression by {{{1=(-1)/(-1)}}};
{{{((-a+3)/((-2)(a+3)))((-1)/(-1))}}}
{{{(-(-a+3))/(-(-2)(a+3))}}}
{{{highlight((a-3)/(2(a+3)))}}}------This is what results if kept in factored form.
-
{{{highlight((a-3)/(2a+6))}}}-------The equivalent in multiplied form.
