Answer:

The answer is 6 and -6

Step-by-step explanation:

The given equation is
$x^2 - kx + 9 = 0 ... (1)$

where a = 1. b = -k, c = a

since the equation (1) has equal roots

$\Rightarrow b^2 - 4ac = 0 \newline\\\Rightarrow (-k)^2 - 4(1)(9) = 0\\ \newline\\\Rightarrow (k)^2 - 36 = 0 \newline\\\Rightarrow k^2 = 36 \newline\\\Rightarrow k = \pm 6$

Hence volume of k = 6, -6
