MCQ
The zeros of the polynomial $x^2-2 x-3$ are :
- ✓$3, -1$
- B$3, 1$
- C$-3, 1$
- D$-3, -1$
✓
Answer
Correct option: A.
$3, -1$
$x^2-2 x-3$
$= x(x - 3) + (x - 3)$
$\therefore (x - 3) (x + 1) = 0$
$\Rightarrow x = 3$ or $x = -1$
$= x(x - 3) + (x - 3)$
$\therefore (x - 3) (x + 1) = 0$
$\Rightarrow x = 3$ or $x = -1$
