If x+2 is a factor of polynomial 5x cube +(k+2)x square - 3kx + 2 then find the value of k.

If x+2 is a factor of polynomial 5x cube +(k+2)x square - 3kx + 2 then

1.	If x+2 is a factor of polynomial 5x cube +(k+2)x square - 3kx + 2 then find the value of k.
Answer» K=3 X=-2,(5×-2)cube +(k+2)-2-3k(-2)-1000-2k-2+6k4k=1000+24k=1002K= 1002/4K=250.5
