Using extended euclidean algorithm find f(x) and g(x) in: f(x)(x^5 + 4x^4 + 6x^3 + x^2 + 4x + 6) + g(x)(x^5 + 5x^4 + 10x^3 + x^2 + 5x + 10) = x^3+1

Expert Solution

Lets denote

We have to find such that

Lets start with our division algorithm.

The last nonzero remainder is which can be written as linear combination of as follows:

(this is written based on the middle equation in the series of equations above)

(this is obtained by substituting the first equation in the series of equations above)

Simplifying, we get:

That is

So as to obtain the desired equation, dividing by 6:

Or

So we get and

Write a program( preferably in C++) using the extended Euclidean algorithm to find the multiplicative inverse of a mod n. Your program should allow user to enter a and n. Note: For this question please make sure the code compiles and runs, it is not copied and pasted from elsewhere( I will be checking!). Thanks
