You can put this solution on YOUR website! Rational roots theorem should show zeros to be -1/2, 2, and 3. If let x equal to 0, this should give the y-intercept.

-----
Possible Roots (zeros) to check according to Rational Root Theorem:
-3,+3,-2,+2,-1,+1,-1/2,+1/2
TEST FOR SOME ROOTS
3 | 2 -9 7 6
|
| 6 -9 -6
---------------------
2 -3 -2 0 linear root x-3
2 | 2 -3 -2
|
| 4 2
------------------
2 1 0 linear root x-2
Other linear root according to result in the synthetic division,
2x+1
The function, factorized is  .
The zeros are 3, 2, -1/2.
You can find the y-intercept.
