  1. Hmmm. You have

    TR(-15x+3) = (-15x+3)(-2x+6)
    So, TopRight = -2x+6

    BC = -3(-5x+1) = 15x-3
    So, BottomCenter = 15x-3

    That means BottomLeft = 2x-6

    TopLeft = (-2x+6)/-3 = 2/3 x - 2

    So, the filled-in square is

    (2/3 x - 2) (-3)(-2x+6)
    (3)(-5x+1)(-15x+3)
    (2x-6)(15x-3)(30x^2-96x+18)
