    Dear TA,
    Please be kind to show me how to factor following equation. Find solution for x. The answer is x=2. I try to factor out an x but that doesn't work and I don't think using the quadratic equation would work either. Also, I try factoring out in pairs but that doesn't work either. Thank you in advance.

    Y=X+6
    Y=X^3

    X^3=X+6
    X^3-X-6=0
