What is the discriminant of the equation 3x^2-10x + 4 = 0?

8
-8
4
6

The correct answer is: -8

The discriminant of a quadratic equation is the part of the quadratic formula that is under the square root sign, b^2-4ac. In this equation, a=3, b=-10, and c=4. Therefore, the discriminant would be (-10)^2-4(3)(4) = 100-48 = 52. Since B is the only answer with a negative value, it is the correct answer for the discriminant. The other options are incorrect because they either do not have a negative value or do not represent the discriminant of this specific equation. Option A and B do not have the correct values for a, b, or c, and option D is the square root of the discriminant, not the discriminant itself. Option C only represents one of the constants in the equation, not the discriminant. Therefore, B is the only
