Step 1
p ( z ) = ( z 3 ) ( z + 4 ) ( z 8 ) then find p ( 5 )
Let assume z = 1;
Now put z = 1 ; p ( 1 ) = ( 1 3 ) ( 1 + 4 ) ( 1 8 ) = ( 2 ) ( 5 ) ( 7 ) = 10
Step 2
We have to find P(5) means z = 5
for this put z = 5 in the P(z).,
P ( 5 ) = ( 5 3 ) ( 5 + 4 ) ( 5 8 ) = ( 2 ) ( 9 ) ( 3 )
P ( 5 ) = 54
P ( 5 ) = 54
