Answer:

12

Step-by-step explanation:

Given,

X - 3 is a factor of p(x)

=> x - 3 = 0

=>. x = 0+3

=>. x = 3

Now,

p(x) = x² + x - k

=> p(3) = (3)² + 3 - k

=> 9 + 3 - k = 0

=>. 12 - k. = 0

=>. -k = 0-12

=>. -k = -12

since, there is minus on both sides,

Therefore,

-k = -12

= k = 12

Therefore, the value of k is 12
