we know that

The discriminant of the quadratic equation of the form

ax^(2) +bx+c=0

is equal to
(b^(2)-4ac )

we have

3 -4x = -6x^(2)

$3 -4x = -6x^(2) \\ -6x^(2)+4x-3=0$

in this problem

$a=-6\\ b=4\\ c=-3$

Substitute in the formula of discriminant

$(b^(2)-4ac )=4^(2)-4*(-6)*(-3)\\ =16-4*18\\ =-56$

therefore

the answer is

the discriminant of the quadratic equation is
