Rational Roots Theorem; synthetic division trying roots -1,-2,-5,1,2,5; maybe +10 or -10.


-1   |   1   -3   6   10
     |       -1   4   -10
     _____________________
         1   -4   10   0 --------  is a (real) root.

Now use quadratic equation skills to get the two other roots.

-----comes from the quotient of the previous synthetic division.

-----these are the two complex roots.

FINISHED.
Degree of equation is three; so only three roots.
