We use polynomials
To find the motion of a particle (thing) under the influence of gravity.

    Newton’s laws of motion
   The three equations of motion are

              1.  v = u + at              2.  s = ut + ½ at              3.  2as = v2 – u 
  These are actually polynomial  equations.

    Polynomial means many terms .  But a polynomial cannot have infinite number of terms. Note : 7 is the term here and not -7 It consists of constants (like 2, -6 or ½) variables (like x and y)
But pi is a polynomial because this is a constant whose value (=1.4142……..) Yes 9 is a polynomial. Only one term is allowed. Polynomial can have no variable at all.
     So,  is not a polynomial.    
     So, is a polynomial 
Polynomials with 1,2 or 3 terms have certain names:
The more a polynomial is of higher order (degree), the more difficult it is to solve. Writing style deg(3x3y-4y )=4
