Question 291673
I have tried SNYDIV to solve "Determine ALL zeros of the polynomial 
P(W) = 6x^4 + 25x^3+ 80x^2 + 5x - 26.  I determined 1/2 is one of four answers.  I have tried +/- 1, +/-2, +/-13, and +/-26.
-------------------------------------------------------
But, the coefficient of the x^4 term is 6.
Try 1/2 and 2/3
P(-2/3) = 0
P(1/2) = 0
