    If a + b + c = 0, then what is the value of

    a3┬а+ b3┬а+ c3┬а- 3abc?
    A -1 Correct Answer Incorrect Answer
    B 1 Correct Answer Incorrect Answer
    D 2 Correct Answer Incorrect Answer

    Solution

    We know that, a3┬а+ b3┬а+ c3┬а- 3abc = (a + b + c)(a2┬а+ b2┬а+ c2┬а- bc - ab - ac) So, a3┬а+ b3┬а+ c3┬а- 3abc = 0 X (a2┬а+ b2┬а+ c2┬а- bc - ab - ac) [Since, a + b + c = 0]
