Question

ab(a²+b²-c²)-bc(c²-a²-b²)+ca(a²+b²-c²)
FACTORISE​

Answer 1

Question:-

ab(a²+b²-c²)-bc(c²-a²-b²)+ca(a²+b²-c²)

FACTORISE

${\pink{\underline{\underline{\bold{Answer:-}}}}}$

ab(a²+b²-c²) -bc(c²-a²-b²) +ca(a²+b²-c²)

ab(a²+b²+c²) +bc(-c²+a²+b²) +ca(a²+b²-c²)

ab(a²+b²+c²) +bc(a²+b²-c²) +ca(a²+b²-c²)

(a²+b²-c²) [ab+bc+ca]

===========================

{a+(b-c)(b+c)} [ab +bc+ca]
