numpy.polysub() :This function helps to find the difference of two polynomials and then returning the result as a polynomial. Each input polynomial must be a sequence of polynomial coefficients, from highest to lowest degree.
Parameters : p1 : Input polynomial 1 : 1x + 2. p2 : Input polynomial 2 : 9x2 + 5x + 4
Return:
Difference of polynomials : (0-9)x2 + (1-5)x + (2-4)

Output:
P1 :
1 x + 2
P2 :
2
9 x + 5 x + 4
P1 - P2 :
2
-9 x - 4 x - 2
