Examples:
    1.
    2 - 3x

    2.
    5x2 - 8

    3.
    -2.16x + 7x3 - 7/2

    4.
    3x5 - SQRT(11)x4 + 4x3 + (5/9)x2 - 133x + 2

    5.
    4.7x8 + 3.1x3 + 9x

    6.
    (x - 3)2 + 6x + 1
    This doesn't really look like the correct format of a polynomial, but when you expand it out, you get
    x2 - 6x + 9 + 6x + 1 = x2 + 10 which is a polynomial.

    7.
    1/x3 +1 is not a polynomial!
