__
Your discriminant of -8 is <em>negative</em>, so it indicates ...
There are two complex roots
_____
<em>Additional comment</em>
We generally study polynomials with <em>real coefficients</em>. These will never have an odd number of complex roots. Their complex roots always come in conjugate pairs.
3x²y²-xy²-2y²
(3x²+2x)+(-3x-2)
x(3x+2)-(3x+2)
(3x+2)(x-1)
y²(x-1)(3x+2)
