Question

multiply the polymials pq（p²-q²+1）

Answer 1

pq × (p²-q²+1)

= p³q-q³p+pq

Answer 2

Answer:

$\huge\boxed{\boxed{soltion}} \\ \\ \\ \implies \: pq( {p}^{2} - {q}^{2} + 1) \\ \\ \implies \: {p}^{3} q - {q}^{3} p + pq \\ \\ \\ that \: is \: your \: answer \\ \\ when \: we \: multiply \: same \: variable \\ then \: it \: added \: into \: its\: power$
