Question

(p – q) (p2 + pq + q2) = p3 – q3 (verify this answer) (proper steps) ( I will mark as a brainlist )

Answer 1

Answer:

step 1 :

p(p²+pq+q²) - q(p²+pq+q²)

=> p³+p²q+pq²-p²q-pq²-q³

p²q-p²q = 0

pq²-pq² = 0

=> p³-q³

Answer 2

Answer:

Answer:

step 1 :

p(p²+pq+q²) - q(p²+pq+q²)

=> p³+p²q+pq²-p²q-pq²-q³

p²q-p²q = 0

pq²-pq² = 0

=> p³-q³
