Are you saying that the characteristic equation for some linear map iswhat are the eigen values for
k^2-8k+-12=0
i got (k-2) (k+3) as eigen values
Most people would read this as either [itex]k^2-8k-12=0[/itex] or [itex]k^2-8k \pm 12=0[/itex]. The first one, [itex]k^2-8k-12=0[/itex], cannot be factored by using integers. However, [itex]k^2-8k+12=0[/itex] can. Which equation you are trying to solve still isn't clear after 13 posts. And I am not the first one to ask you so please read the posts carefully.morbello said:k^2-8k+-12=0
