As x = 1/2 ....is a zer of polynomial ...pit it into the polynomial..
1 /2 = 8 × (1/2)^3 - k ..
so k = 1/2.....
1 /2 = 8 × (1/2)^3 - k ..
so k = 1/2.....

P(x)8x cube-k
P(1/2)=8×1/8-k
P(1/2)=1-k
1-k=0
-k=-1
K=1
P(1/2)=8×1/8-k
P(1/2)=1-k
1-k=0
-k=-1
K=1
OTHER wise my answer will be okk if i got that p of x not as x
i consider p of x as x .therefore...
