Answer 1

Explanation:

According to the Remainder theorem, when a polynomial p(x)is divided by

(x−

a)

, then the remainder is the value of

p(x)

at

x=

a

Here

p(x)=

3x

2

+

kx+

6

When it is divided by its factor

(x+

3)

,

Remainder is

=

p(−3)=

0

3(−3)

2

+ (−3)k+ 6= 0

27− 3k+ 6= 0

33− 3k= 0

3k= 33

k= 11
