Answer 1

Step-by-step explanation:

$p(x) = x - 3 \\ \: \: \: \: \: x - 3 = 0 \: (by \: remainder \: therom) \\ \: \: \: \: x = 3 \\ p(3) = {x}^{2} + kx + 9 \\ \: \: \: \: 0 \: = {3}^{2} + 3k + 9 \\ \: \: \: \: 0 = 9 + 9 + 3k \\ \: \: \: \: 0 = 18 + 3k \\ \: \: \: \: - 18 = 3k \\ \: \: \: \: \frac{ - 18}{3} = k \\ \: \: \: \: \: \: \boxed{k = - 6}$
