Let W be the set of P4 consisting if all polynomials satisfying the conditions p(-2)=0.
a.) prove that W is a subspace of P4 by checking all 3 conditions in the definition of subspace.
b.) Find a basis for W. Prove that your basis is actually a basis for W by showing it is both linearly independent and spans W
c.) what is the dim(W)
