f(x) = x^4 - 7x^3 -3x^2 + 19x + 14

Help

- Math - potential zero -
**Reiny**, Wednesday, June 1, 2011 at 11:14pmtrying a few factors of 14, I found

f(-1) = 0 and f(2) = 0

so after 2 consecutive synthetic divisions, that left me with

(x+1)(x-2)((x^2 - 6x - 7)

= (x+1)(x-2)(x+1)(x-7)

so we have a double zero at x=-1

and two more zeros at 2 and 7
