Homework Statement
For each real linear space below, find a basis and its dimension.
[...]
(c) {2nd degree polynomials p such that p(2) = 0}
Homework Equations
Definition of basis and dimension.
The Attempt at a Solution
So, we know that
p(x) = ax2 + bx + c
and
p(2) = 0 = 4a + 2b + c
so that we have
p(x) = ax2 + bx - 4a -2b.
But where do I go from here?
