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
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
