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

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

    Solution

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