Exercise Set
1) Consider the following polynomials in R[x]:
f (x) = 4x3 + 28x2 − 55x + 9 , g(x) = x2 + 7x − 14
By applying the Euclidean algorithm to f (x) and g(x):
a) determine the greatest common divisor of f (x) and g(x), gcd(f, g);
b) determine polynomials a(x) and b(x) in R[x] such that gcd(f, g) = a(x)f (x) + b(x)g(x).
2) Consider the following matrices:
╱ 、 ╱ 、 ╱ 、
( 0 0 −7. , ( 0 0 −9. , ( 0 0 −7.
For each of these matrices, determine, with justification, the minimal polynomial of the matrix.
3) Consider the following complex matrix:
M = ╱、
