    twice a number subtracted from the square root of the same number

    The phrase a number means an arbitrary variable, let's call it x:
    x

    Twice a number means we multiply x by 2:
    2x

    Square root of the same number:
    sqrt(x)

    twice a number subtracted from the square root of the same number
    sqrt(x) - 2x
