Question

If product of the roots of the equation

3x² – 4x + (loga² – log(–a) + 3) = 0 is 1, then 'a' =

• A. Not possible
• B. – 1
• C. 1
• D. None of these

Answer 1

Answer: (B)

– 1

Answer 2

\a>0 Ž a < 0 ....(i)

Now $\frac{\log a^{2}–\log(–a) + 3}{3}$=1

Ž a² = – a, Ž a = 0, – 1 ..(ii), form (i) & (ii) Ž a = – 1
