Let p(x) = 2x4 - 3x3 - 3x2 + 6x - 2
Since x = zeroes of the given polynomial p(x),
(x + ) (x - ) will be a factor or x2 - 2 will be a factor of p(x).
We have:
2x2 - 3x+ 1 = 2x2 - 2x - x + 1
= 2x (x - 1) - 1(x - 1)
= (2x - 1) (x - 1)
So, p(x) = (x + ) (x - ) (2x - 1) (x - 1)
Thus, the other zeroes of p(x) are and 1.
