mx + 4 is exactly divisible by (x-2).
plz ans fast​

Answer 1

Answer:

18  or  12

Step-by-step explanation:

Your question is something wrong.

but you can take it.

The polynomial is exactly divisible by (x-2).

that means f(2)=0

=>$2^{3}+3(2)^{3} -m(2)+4=0$

=>8+24-2m+4=0

=> 2m=36

=>m= 18

otherwise,

The polynomial is exactly divisible by (x-2).

that means f(2)=0

=>$2^{3}+3(2)^{2} -m(2)+4=0$

=>8+12-2m+4=0

=> 2m=24

=>m= 12
