subspace of M2x2

[@mikem9270]

My professor has an extremely heavy accent, not the best handwriting, and makes up the hw questions himself which usually has a couple of typos with no way to check our solutions. He's very confusing so I rely heavily on the internet for help. You made this so simple I almost want to cry. Thank you!
