​

Answer 1

Answer:

3

Step-by-step explanation:

x+3=0

x=-3

(-3)^3+(-3)^2-5*(-3)+k=0

-27+9+15+k=0

-3+k=0

k=3

Answer 2

Answer:

Thanks for your question...

Your required answer :

• Given : x + 3 is factor of x³ + x² - 5x + k

• x + 3 = 0
• x = -3

Now , put the value of x in divided.

• ( -3 )³ + ( -3 )² -5 ( -3 ) + k = 0
• ( -27 ) + 9 + 15 + k = 0
• ( -27 ) + 24 + k = 0
• 24 + k = 27
• k = 27 - 24
• k = 3
