Answered by maham237 @ 02/12/2020

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 $-56$
