Question

if (x+6) is a factor of the polynomial $x2$+mx+24, than find the valve of m

Answer 1

if (X+6)is the factor of px
then (X+6)=0
therefore X=-6

2x+mx+24=0
2(-6)+m(-6)+24=0
-13-6m+24=0
-6m=-11
m=11/6

Answer 2

m=10 by due method♀

As x+6 is factor we can take x=-6 and substitute it with the following equation
