    Question Equation simplification

    Hi friends,

    I have a following equation :

    x = x2 - [(N-1) * 2], where N = 11

    that becomes:

    x = x2 - (20)

    My question:
    If possible, how can we derive the value of x in the equation x = x2 - (20) ?

    Thanks in advance,
    Regards.

    Write it as x^2 - x - 20 = 0 and then factorise or use the Quadratic Formula.
