Final answer:
The discriminant for the given quadratic equation -2x + 3x - 1 = 0 is 1. Hence the correct answer is option A
Step-by-step explanation:
The discriminant for a quadratic equation of the form ax²+bx+c=0 can be calculated using the formula: discriminant = b² - 4ac. In this case, the equation is -2x + 3x - 1 = 0, so a = -2, b = 3, and c = -1. Substituting these values into the formula, we get: discriminant = 3² - 4(-2)(-1) = 9 - 8 = 1.
Therefore, the discriminant for the given equation is 1. Answer B is correct.
