Question

As if a + b + c = 2,ab + ab + ca = -1 & abc = -2, find the value of a3+b3+c3.

Answer 1

Answer:

I think the answer will be 8

Step-by-step explanation:

Given, a+b+c=2

To find, a3+b3+c3

So we can also write it as (a+b+c)3 as Power 3 is common in all of them

and the value of a+b+c is 2, So

(2)3=2×2×2 (when expanded)

which equals to 8
