    Given first equation,

    (1) 2x^⁴+12x+4

    it's a polynomial of degree (4)

    known as Tetra polynomial

    (2) x^³+4x

    it's a polynomial of degree (3)

    known as cubic polynomial

    (3) 3/x^⁴-6x³

    it's not a polynomial because of power of X is (-4) which a negative

    so it's not a polynomial

    (4) x^⁴/3-6

    it's a polynomial of degree (4)

    known as Tetra polynomial
