Question: A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i

A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation 1. For the complex number a + bi, a is called the real part, and b is called the imaginary part. For two complex numbers z-al + bli,y a2 + b2i, the addition (z + y) and the multiplication (x x y) are defined as follows
