Factorise (a²-b²)³-(b²-c²)³+(c²-a²)³

Posted by Manya Singh 5 years, 3 months ago

CBSE > Class 09 > Mathematics

1 answers

Yogita Ingle 5 years, 3 months ago

(a²-b²)³+(b²-c²)³+(c²-a²)³=3(a+b)(b+c)(c+a)(a-b)(b-c)(c-a)
We know that if x + y + z =0 then x³ + y³ + z³ = 3xyz
Here x = a²-b², y = b²-c² and z = c²-a²
a²-b² + b²-c² + c²-a² = 0
Hence (a²-b²)³+(b²-c²)³+(c²-a²)³ = 3(a²-b²)(b²-c²)(c²-a²)³
= 3(a + b)(a − b)(b + c)(b − c)(c + a)(c − a)
= 3(a + b)(b + c)(c + a)(a − b)(b − c)(c − a)
