Solving Equations With Complex Numbers Youtube Why do we need imaginary numbers? motivation explained for introducing the imaginary unit i and using complex numbers. examples simplifying and working with. Welcome to the world of imaginary and complex numbers. we'll learn what imaginary and complex numbers are, how to perform arithmetic operations with them, represent them graphically on the complex plane, and apply these concepts to solve quadratic equations in new ways. For example, the real number 5 is also a complex number because it can be written as \(5 0i\) with a real part of 5 and an imaginary part of 0. hence the set of real numbers, denoted r, is a subset of the set of complex numbers, denoted c. adding and subtracting complex numbers is similar to adding and subtracting like terms. To divide complex numbers, we apply the technique used to rationalize the denominator. multiply the numerator and denominator by the conjugate of the denominator. the result can then be simplified into standard form \ (a bi\). example \ (\pageindex {8}\): divide \ (\frac { 1 } { 2 3 i }\). solution.
