Let

a, b

be positive real numbers. If the equations

x^2+a x+2 b=0

and

x^2+2 b x+a=0

have real roots, then minimum value of

a+b

View answer and explanation

Correct option: B

Option B (6) is correct because the minimum value of a+b is 6, derived from the conditions for real roots of the given quadratic equations.
