solve this one

If it`s zeroes are 2 and -2 the ( x - 2) and ( x + 2) are its factors . i.e ( x - 2) . ( x + 2) =  x²-2 is a factor.

Now divide 2x⁴-3x³-3x²+6x-2.I by  x²-2 by the method of long division. You will get a quadratic equation .

That , I am sure you know how to factorise

(i) either by splittin middle term

(ii) or completing squares

(iii) or by formula
