    Not a polygon

    Step-by-step explanation:

    [ (3x+12) • (4x+4) ] - (3x+8) - (4x)

    [12x² + 12x + 48x + 48] - 3x - 8 - 4x

    12x² + 60x + 48 - 7x - 8

    12x² + 53x + 40

    This is a degree 2 (quadratic) polynomial, not a polygon.

    A polygon is an n-sided figure.

    Example: A rectangle - -> A four-sided polygon
