Find the product:(p2 – q2) (2p + q)

1.	Find the product:(p2 – q2) (2p + q)
Answer» (p² – q²) (2p + q) = p² (2p + q) – q² (2p + q) = p² x 2p + p² x q – q² x 2p – q² x q = 2p³ + p²q – 2q²p – q³

Answer»

(p² – q²) (2p + q)

= p² (2p + q) – q² (2p + q)

= p² x 2p + p² x q – q² x 2p – q² x q

= 2p³ + p²q – 2q²p – q³
