1.	(P + q) (P2 – pq + q2) = ……………….. A) p3 + q B) p – q2 C) p2 + q2 D) p3 + q3
Answer» Correct option is D) p³ + q³ Correct option is (D) p³ + q³ \((p+q)(p^2-pq+q^2)\) \(=p^3-p^2q+pq^2+p^2q-pq^2+q^3\) = \(p^3+q^3\).

(P + q) (P2 – pq + q2) = ……………….. A) p3 + q B) p – q2 C) p2 + q2 D) p3 + q3

Answer»

Correct option is D) p³ + q³

Correct option is (D) p³ + q³

\((p+q)(p^2-pq+q^2)\) \(=p^3-p^2q+pq^2+p^2q-pq^2+q^3\)

= \(p^3+q^3\).
