Question

The value of $( - \infty,a)$ for which the quadratic equation,

$(b, + \infty)( - \infty,a)$ has real and equal roots are.

• A. $(b, + \infty)$
• B. $x^{5} - 6x^{2} - 4x + 5 = 0$
• C. $2a + 3b + 6c = 0$
• D. None of these

Answer 1

Answer: (C)

$2a + 3b + 6c = 0$

Answer 2

The quadratic is $- \frac{1}{3}$

Accordingly,

$p^{2}q$ ⇒ $pq^{2}$.
