Question

What value of k will make (x+3) a factor of x^2 + x + k?

Answer 1

Answer:

k = -6

Step-by-step explanation:

( x + 3) is a factor of equation,

x = -3

= x^2 + x+k

= (-3)^2 +(-3)+k

= 9 - 3 + k

= 6+k

k = -6

Answer 2

To find value of k put value of factor in given equation.

x +3 = 0

x = -3

x² + x + K = 0

(putting value of x)

(-3)² + (-3) + K = 0

9 -3 +K = 0

K = -6
