Question

bc(a²+1) +a(b2+c²) factorise​

Answer 1

Answer:

Step-by-step explanation: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)

Or,

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

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

Answer 2

Answer:

a2bc+bc+ab2+ac2

a2bc+ac2+ab2+bc

ac(ab+c)+b(ab+c)

ac+b=0,ab+c=0
