Answer 2

$\sf{Answer}$

Step by step explanation:-

p³ -(p+1)³

We have to solve

We know that (p+1)³ =

It is in form (a+b)³ = a³+b³+3ab(a+b)

Similarily

(p+1)³ = p³+1³ +3p(p+1)

(p+1)³ = p³ + 1+3p²+3p

Now Simplify

p³ -(p+1)³

p³ -(p³+3p²+3p+1)

p³ -p³-3p²-3p-1

-3p²-3p-1

So, p³-(p+1)³ = -3p²-3p-1
