Question

If a + b = -c, then a3 + b 3+ c3​

Answer 1

Answer:

Heya user........................ ❤

Given,

a+b = -c

To find:

a^3 + b^3 + c^3

We have to use this formula.

(a^3 + b^3) = (a+b)^3 - 3ab (a+b)

Here,

a^3 + b^3 + c^3

= (a+b) ^3 - 3 ab (a+b) + c^3

= (-c)^3 - 3ab × (-c) + c^3

= -c^3 + 3abc + c^3

= 3 abc

So, 3abc is the correct answer.

Hope it’s helpful...... ☺
