p(x+2)=2x 2+mx+4
that implies x+2=0
x=-2
p(-2)=2x 2+mx+4
0=2(-2)+m(-2)+4
0=-4+(-2m)+4
0=-2m
m=0/-2
m=0
that implies x+2=0
x=-2
p(-2)=2x 2+mx+4
0=2(-2)+m(-2)+4
0=-4+(-2m)+4
0=-2m
m=0/-2
m=0

sorry
its ok
the answer is 2(-2) 2+m(-2)+4=0 , 2*4-2m+4=0 , 8-2m+4=0 , 12-2m=0 , 12=2m ,m=12/2 that implies m=6
