Question

If (a+b+c) = 0 Then find the value of a , b and c

- with proper explanation Please -.- ​

Answer 1

Answer:

So, a + b + c = 0

or, a = -b -c

Now, a + b + c = 0

or, c = -a -b

Again, a + b + c = 0

or, b = -a -c

For these values of a, b and c the expression a+b+c will be zero.

Answer 2

Answer:

please mark me brain list

Step-by-step explanation:

We know,

a

3

+b

3

+c

3

−3abc=(a+b+c)(a

2

+b

2

+c

2

−ab−bc−ca)

Putting a+b+c=0 on RHS, we get,

a

3

+b

3

+c

3

−3abc=0

⟹a

3

+b

3

+c

3

=3abc, Hence proved
