Answer Two things are important to note. First, the zeros 1 + 2i and 1 − 2i are complex conjugates. This will always be the case when we find non-real zeros to a quadratic function with real coefficients. Second, we could write f(x) = x2 − 2x + 5 = (x − (1 + 2i))(x − (1 − 2i)) graph sampling aggregation network https://waltswoodwork.com
