Question

$p {}^{3} - (p + 1) {}^{3}$
​

Answer 1

Answer:

Use binomial theorem \left(a+b\right)^{3}=a^{3}+3a^{2}b+3ab^{2}+b^{3} to expand \left(p+1\right)^{3}.

p^{3}-\left(p^{3}+3p^{2}+3p+1\right)

To find the opposite of p^{3}+3p^{2}+3p+1, find the opposite of each term.

p^{3}-p^{3}-3p^{2}-3p-1

Combine p^{3} and -p^{3} to get 0.

-3p^{2}-3p-1
