Question

plz solve the question ASAP​

Answer 1

If D=0

Thus the roots are equal.

$\alpha = \beta \\ \alpha + \alpha = \beta + \alpha = > 2 \alpha = \alpha + \beta \\ also \: \alpha - \beta = 0$

But the last equation,

$\alpha + \beta = 0$

is not true thus Answer is option D

Answer 2

The right answer is (d)...

$\alpha + \beta = 0$

bcoz when D=0, roots are equal.

and equal cannot add up to 0.
