Question

p³-121p=p(p+11)(p-11)​

Answer 1

Step-by-step explanation:

p³-121p

=p(p²-121)

=p(p²-11²)

=p(p-11)(p+11)

L.H.S=R.H.S

Answer 2

Answer: Lets do this really quick

Here we can take any value of P

let me take P=0

than L.H.S=R.H.S

and if p=11

than (11)^3- 121*11=11*22*0

this is also true 0=0
