Find the valus of the discriminant of y=-3x^2+4x-2 and determine the number of solutions

Calculation of the discriminant of the polynomial: 2−4⋅x+3⋅x²+yApplying the formula to calculate the discriminant Δ=b2−4⋅a⋅c with : a=3, b=−4,c=2+yΔ=(−4)²−4⋅(3)⋅(2+y)=16−12⋅(2+y)=−8−12⋅yThe discriminant of the polynomial 2−4⋅x+3⋅x²+y is equal to −8−12⋅y

False because how does that work?
