Question

p³ -(p+1)³ solve step by step​

Answer 1

Step-by-step explanation:

Given ,

p³ - ( p + 1)³

according to formula of a³ - b³

a³ - b³ = ( a + b) ( a² + ab + b²)

then,

( p - p - 1) ( p² + 2p+ 1 + ( p + 1)²}

-1 ( p² + 2p + 1 + p² + 2p + 1)

-p² -2p - 1 - p² -2p -1

-4p - 2p² - 2 answer

Answer 2

(a+b)³=(a+b)(a²+b²-ab)

so..

p³-(p+1)(p²+1-p)

p³-p³-p+p²-p²-1+p

-1
