MCQ
$(x - 1) (2x - 1) = 0$ discriminant of the given equation is :
- A$0$
- B$2$
- ✓$1$
- D$3$
✓
Answer
Correct option: C.
$1$
$(x - 1) (2x - 1) = 0$
$ 2 x^2-3 x+1=0 $
$ D=b^2-4 a c $
$ D=(-3)^2-4 \times 2 \times 1$
$D = 9 - 8$
$D = 1$
$ 2 x^2-3 x+1=0 $
$ D=b^2-4 a c $
$ D=(-3)^2-4 \times 2 \times 1$
$D = 9 - 8$
$D = 1$
