Homework Statement
Let A be an nxn matrix belonging to R and x be a vector of length k belonging to R. Find the first column of
M = (A − x1I)(A − x2I)...(A − xrI) using a sequence of GAXPY’s operations.
Homework Equations
GAXPY: General matrix A multiplied by a vector X plus a vector Y
The Attempt at a Solution
I tried to figure it out by writing A and x explicitly and then multiplying (A-x1I) ...(A-xrI) but it was so messy and i did not get any result, i want a hint how to start the solution.
