How many complex zeros does the function #f(x) = x^12 + x^9 + x^7 - 2x^2# have?
According to the fundamental theorem of algebra, every polynomial of degree
Your function is a 12th degree polynomial, so it has twelve complex zeroes.
Note: a complex number is a number of the form
The 12 complex zeroes of your function include four real zeroes and eight imaginary zeroes.
