Question 703867
A restart with proper notation will be this:


Your trying to represent this:
(3x^2+10x+8)/(-x-2)=-2
which would appear on paper, something more like,
{{{(3x^2+10x+8)/(-x-2)=-2}}}


Next can be,
{{{(3x+4)*(x+2)/(-(x+2))=-2}}}
{{{(3x+4)*(x+2)/(x+2)=2}}}
and the factors of x+2 can cancel,
{{{3x+4=2}}}
{{{x=-2/3}}}
