Perform synthetic division to find the quadratic, possibly factorable, factor.
3________________|______1______-5______11_______-15
_________________|
_________________|_____________3_______-6________15_________
_______________________1______-2_______5_________0
The remainder there is 0.
The quotient means, and not factorable.
Those roots are
. These are the two other zeros.
