    The square of the difference of n and 2, increased by twice n

    The difference of n and 2:
    n - 2
    The square of the difference of n and 2 means we raise (n - 2) to the 2nd power:
    (n - 2)^2

    Twice n means we multiply n by 2:
    2n

    The square of the difference of n and 2, increased by twice n
    (n - 2)^2 + 2n
