Discriminant of the equation is
Discriminant of the equation \( -3 x^{2}+ \) \( 2 x-8=0 \) is
- A. -92
- B. -29
- C. 39
- D. 49
Step-by-step solution
For the quadratic equation -3x^2 + 2x - 8 = 0, the coefficients are a = -3, b = 2, c = -8. The discriminant D = b^2 - 4ac = 2^2 - 4(-3)(-8) = 4 - 96 = -92.
