Hi,
Can anyone help me find the zeros of the following equation:
f(x) = 2x^3 + x^2 - 20x + 1
I used the rational zero therom to determine that the *possible* zeros are the following:
+/- 1
+/- 1/2
I then tried using synthetic division to test if any of the above *possible* zeros actually are zeros. For all of the possibilities (+1, -1, +1/2, -1/2), I get a remainder in my synthetic division.
If anyone could help me with this, I'd really appreciate it.
Thanks in advance,
Paul
