The vector space P3 is the set of all at most 3rd order polynomials with the "normal" addition and scalar multiplication operators.

In this video we work with a subset of elements from P3 and formally show that it is a subspace. Since P3 is already a vector space, to show this subset is a subspace we only need to check 3 properties, not all 10 normal vector space properties. We work through each of these 3 properties to show the subset is indeed a subspace.
