MCQ
The discriminant of $4x^2+ 3x - 2 = 0$ is:
- A$-23$
- ✓$41$
- C$39$
- D$-31$
✓
Answer
Correct option: B.
$41$
Here,
$a = 4, b = 3, c = -2$
Discriminant = $b^2- 4ac$
$= (3)^2- 4 \times 4 \times (-2)$
$= 9 + 32 = 41$
$a = 4, b = 3, c = -2$
Discriminant = $b^2- 4ac$
$= (3)^2- 4 \times 4 \times (-2)$
$= 9 + 32 = 41$
