# Show that p – 1 i

Answer :

let h (p) = 𝑝 10 − 1,and g(p) = 𝑝 − 1

Putting g (p) = 0 𝑝 − 1 = 0 𝑝 = 1

According to factor theorem if g(p) is a factor of h(p) , then h(1) should be zero

h(1) = (1)10 − 1 = 1 − 1 = 0

g (p) is a factor of h(p).

Now, we have h (p) = 𝑝 11 − 1, g (p) = 𝑝 − 1

Putting g (p) = 0 𝑝 − 1 = 0 𝑝 = 1

According to factor theorem if g (p) is a factor of h (p) ,

Then h(1) = 0

(1)11 – 1 = 0 hence g (p) the factor of h (p)
