I just started learning Algebra 2, and came across the Fundamental Theorem of Algebra.
Here is how my Textbook defines it:
Every Single-Variable Polynomial Function of Degree $n \ge 1$ has at least one zero in the the set of complex numbers.
I cannot really comprehend this rule.
Take, for example, the polynomial $f(x) = x^2 + 3x + 2$ When factored, we get $(x + 2)(x + 1)$
The roots are $ x = -1, -2 $
There are no complex roots in this equation. Doesn't that disprove the Fundamental Theorem of Algebra?
