Multiplying and dividing complex numbers
We will continue to explore other types of operations on complex numbers. This section will focus on performing multiplication and division on complex numbers.
Basic Concepts: Exponents: Zero exponent: a0=1, Rationalize the denominator , Find the difference of squares: (a−b)(a+b)=(a2−b2)
Related Concepts: Imaginary zeros of polynomials
