Question

simplfy (p³+q³) - (p³-q³) -6pq (p²-q²)​

Answer 1

$= ({p}^{3} + {q}^{3} ) - ( {p}^{3} - {q}^{3} ) - 6pq( {p}^{2} - {q}^{2} ) \\ = {p}^{3} + {q}^{3} - {p}^{3} + {q}^{3} - 6 {p}^{3} q + 6p {q}^{3} \\ = 2 {q}^{3} - 6 {p}^{3} q + 6 p {q}^{3}$

Answer 2

Answer:

Hii Mate, Here is your answer :

=> 2q³ – 6p³q + 6pq³

Step-by-step explanation:

=> (p³ + q³) – (p³ – q³) – 6pq (p² – q²)

=> p³ + q³ – p³ + q³ – 6p³q + 6pq³

Eliminate the opposites, we get

=> q³ + q³ – 6p³q + 6pq³

=> 2q³ – 6p³q + 6pq³

HOPE IT HELPS YOU !!

HAVE A NICE DAY !!
