Complex Numbers
Complex Numbers:
A complex number is a number that can be expressed in the form of a+bi, (a and b are real numbers) and (i) is imaginary.
Fundamental Theorem of Algebra (FTA) says that A polynomial function f(x) of degree n (where n>0) has n complex solutions, counting multiple solutions for the equation f(x)=0. It only tells us how many solutions exist for a given polynomial function.
