For any quadratic equation: ax^2+bx+c =0 ....[1]

then;

the discriminant is given by:

D = b^2-4ac

Given the equation: 3x^2-10x=-2

we can rewrite this equation as: 3x^2-10x+2=0

On comparing the given equation with equation [1] we have;

a = 3 , b = -10 and c = 2

then;

D = (-10)^2-4(3)(2)

D = 100-24 = 76

therefore, the discriminant of 3x^2-10x=-2 is 76

The correct answer would be -1/4. I am sorry that is not one of the choice but by doing the math correctly, -1/4 is the correct answer.
