I'm trying to show that a set W of polynomials in P(adsbygoogle = window.adsbygoogle || []).push({}); _{2}such that p(1)=0 is a subspace of P_{2}. Then find a basis for W and dim(W).

I have already found that the set W is a subspace of P_{2}because it is closed under addition and scalar multiplication and have showed that. The thing i'm stuck on is finding a basis of W and the dim(W), but i think if i figure out how to find the basis i would be able to see what the dim(W) is. So my question is can anyone give me a hint on how to find the basis for W? Thanks
