3 is a zero of f(x)=2x^3-3x^2-11x+6. Use synthetic division to find the zeros of f.
....._________________
3 |2 - 3 - 11 + 6
..............6 + 9 - 6
......------------------
......2 + 3 - 2 + 0
;
so we have
2x^2 + 3x - 2 = 0
Factors to
(2x - 1)(x + 2) = 0
Two solutions
2x = 1
x =
and
x = -2
:
:
The zeros: -2, +, +3
