    Can anyone provide me "steps" as to how this is to be worked out? Thanks

    f(x) = (1-q1-q2)*q1-c*q1

    The first derivative, with respect to q1 of this function is:

    1-2q1-q2-c

    And the second is -2

    The stationary point is at q1 = 1-q2-c/2

    The easiest way to see this is to expand the bracket then differentiate with respect to q1 in the normal manner.

    how do i expand this?
    You know how to expand brackets, right?

    Also, it's f(q_1) and not f(x)
