Answer 1

x3-y3=(x-y)(x2+y2+xy)

x3+y3=(x+y)(x2+y2-xy)

Answer 2

Good Morning!

( a³ - b³ ) = ( a - b ) ( a² + b² + ab )

Q.46

1) a³ - 2√2b³

a³ - √8 b³

Becoz √8 = √(4×2) = 2√2

a³ - {√(2)b}³

Becoz √(2)³ = √(8)

( a - b ) { a² + b² + √2 ab }

2)

a³ + b³ = ( a + b ) ( a² + b² - ab )

p³q³ + 343

p³q³ + 7³

(pq + 7 ) { (pq)² + 7² - 7pq }

(pq + 7 ) { (pq)² + 49 - 7pq }
