21) Solve the following:
[12M]
Find the value of m ,if x+6 is factor of the polynomial +3x+m.
​

Answer 1

4x + 6 + m is answer correct

Answer 2

Answer:

x−1) is a factor of 3x  

2

+mx

Then upon dividing it. The remainder should be equal to zero ⇒1                        

x−1∣3x  

2

+mx∣3x

          3x  

2

+3x

_______________

   mx+3x

∴mx+3x=0

⇒(m+3)x=0

⇒m+3=0 or  x=0

⇒m=−3
