Question

:- (a+b) (a-b) + (b+c) (b-c) + (C+a) {C-a)​

Answer 1

Step-by-step explanation:

a^2 -b^2 +b^2 -c^2+c^2 -a^2

=0

Answer 2

Answer:

0

Step-by-step explanation:

a+b * a- b = à²- b²

a²-b² + (b+c)*(b-c)=b²-c²

b²-c² + (c+a*c-a)= c²- a²

now: a²-b²+ b²-c²+c²-a²=0

any confusion?

hope it'll help
