Question

7. If a, B are the roots of the quadratic equation (x + m) (x + n)-k=
O then find the roots of the equation (x + a) (x +B) + k=0.​

Answer 1

Answer:

Viete's theorem states that for the roots and of a quadratic equation : ax²+bx+c =0

AND

x1 +x2 = -b/a

x1 × x2 = c/a

Thus according to the above . So, we are basically asked whether .

(1) b<0. Not sufficient.

(2) c<0. Directly answers the question. Sufficient.
