    The gist of the Fundamental Theorem of Algebra is that a polynomial with complex coefficients (real numbers are also complex!) of degree n will have exactly n-complex roots. What's the degree of this polynomial?

    That's right, so it must have that many complex roots.

    ok, so it would have about 4 zeros, right?

    not about... EXACTLY four zeros. This is true as long as we're working with complex roots.
