comment Eigenvectors and the relationship between variables in a system of equations.
Wow, so when I have a complex number in the denominator I have to multiply by it's conjugate instead of treating it like normal numbers?

@AndréNicolas If you have time, could you explain why elementary row operations affect the eigenvalues / eigenvectors of a matrix?

@JimmyK4542 Thank you! I forgot to include the 0 coefficient when I used synthetic division.

comment Factoring cubic polynomials with missing terms.
For the divisors of 4, do I have to check both positive and negatives? And is Euclidean division the same as synthetic division?

comment Why do these vectors not span the given space?
I'm still a little confused as to why $H$ is not a span of the three vectors if $v_1$ and $v_3$ are not in $H$. Is this because the second and third entries in $v_1$ and $v_3$ are not equal? Or is it that when an element is not in $H$, then it can't span $H$?

@MichaelAlbanese $H$ is the set of vectors whose 2nd and 3rd entries are equal.
