Step-by-step explanation:

It is given that 2+3,2−3 are two zeroes of the polynomial f(x)=2x4−9x3+5x2+3x−1

∴(x−(2+3))(x−(2−3))=(x−2−3)(x−2+3)

=(x−2)2−(3)2

=x2−4x+4−3

=x2−4x+1

∴(x−(2+3))(x−(2−3))=x2−4x+1 is a factor of f(x)

Now divide f(x) by x2−4x+1

∴f(x)=(x2−4x+1)(2x2−x−1)

Hence, the other two zeroes of f(x) are the zeroes of the polynomial 2x2−x−1

2x2−x−1=(2x+1)(x−1)

Hence, the other two zeroes are −21,1.
