Question

find the value of K when x +2 is a factor of 2×2 + 6x + K​

Answer 1

$\huge \star \underline \pink{answer}$

x+2=0

x=-2

5+(6)(-2)+k=0

5-12k=0

-12k=-5

k= 5/12

Answer 2

Answer:

K=4

Step-by-step explanation:

since ( x +2) is a factor of f(x)= ( 2x² + 6x + K)​ so by

factor theorem

f(-2)=0

2(-2)²+6(-2)+K=0

8-12+K=0

K=4
