Polynomial


A polynomial is an expression of the form

 

  f(x) =  anx,an−1xn−1, an − 2xn−2 ,......,+ a1x + awhere n is a positive integer and  a0,a1, a2,......,aare constants (real numbers). In the above polynomial   anx,an−1xn−1, an − 2xn−2 ,......,aare known as the terms of the polynomial and  an ,an−1, an − 2 ,......,a0  are their respective co-efficients.  e.g .,

  5x3 − 4x2 + x − √2  is a polynomial in the variable x.
