P(1) = 1*3+7*2-4*1+1 = 14
P(-1) = -1*3+7*2-4*-1+1 = 16
P(2) = 2*3+7*2-4*2+1 = 13
P(1) * P(-1) * P(2) = 14*16*13 = 2912
P(2) + P(-1) = 13+16 = 29

p(2)=2³+7(2)²-4(2)+1=8+28-8+1=29
p(-1)=(-1)³+7(-1)²-4(-1)+1=-1+7+4+1=11
p(1)=(1)³+7(1)²-4(1)+1=1+7-4+1=5
p(2)+p(-1)
29+11=40
p(-1)=(-1)³+7(-1)²-4(-1)+1=-1+7+4+1=11
p(1)=(1)³+7(1)²-4(1)+1=1+7-4+1=5
p(2)+p(-1)
29+11=40
