You can put this solution on YOUR website! Use synthetic division to check for possible roots, -10,-5,-2,-1,1,2,5,10.
If you need help with synthetic division, say so; but it is easy to learn to do.
Roots found should be -1 and +2. These are the RATIONAL real roots.
Equation is  ;
There are two other complex solutions, but if you want just the real number solution,s then x=-1 or x=2.
