Answer to Question #305397 in Python for NST

Question

Add two polynomials

Given two polynomials A and B, write a program that adds the give

two polynomials A and B.

Output

Print the addition of polynomials A and B.

If the term with highest degree is negative, the term should be represented as -Cix^ ^ Pi .

For the term where power is 1 represent it as C1x instead of Cl*^ ^ 1 .

If the degree of polynomial is zero and the constant term is also ero, then just print 0 to represent the polynomial. For Lerm Cix^ ^ p i if the coefficient of the term Ci is 1, simply print x ^ P * i

instead of 7x p1

Explanation

If M = 4 and for polynomial A

For power 0, co-efficient is 5

For power 1, co-efficient is 0

For power 2, co-efficient is 10

For power 3, co-efficient is 6.

If N = 3 and for polynomial B

For power 0, co-efficient is 1

For power 1, co-efficient is 2

For power 2, co-efficient is 4.

And if result is zero print 0.

And if result has 1x solution it only x.
