If the roots of the equation

x^2+2 a x+b=0

are real and distinct and differ by at most

2 m

, then

b

lies in the interval

View answer and explanation

Correct option: C

\left[a^2-m^2, a^2\right)

Option C ([a^2-m², a²)) is correct because the roots are real and distinct, and their difference is at most 2m, leading to the given interval for b.
