always true

Step-by-step explanation:

Assuming that you mean by true that it has solutions

we have

3x^2-9x-2=0

to know if it has real solutions we need to know if

b^2-4ac

is greater, equal or less than zero

if it's greater it's always

if it's equal it's sometimes

if it's less it's never

so

b=-9

a=3

c=-2

(-9)^2-4(3)(-2)\\\\=81+24\\\\=105

so it's always
