WebbTo simplify, we combine the real parts, and we combine the imaginary parts. (a+bi)(c+di)= (ac−bd)+(ad+bc)i ( a + b i) ( c + d i) = ( a c − b d) + ( a d + b c) i How To: Given two complex numbers, multiply to find the product. Use the distributive property or the FOIL method.

WebbThe reason for getting rid of the complex parts of the equation in the denominator is because its not easy to divide by complex numbers, so to make it a real number, which is a whole lot easier to divide by, we have to multiply it by a number that will get rid of all the imaginary numbers, and a good number to use is the conjugate. Comment WebbThe answer is you need to invent a whole new concept of numbers and this thingy called the complex plane. Read this http://www.purplemath.com/modules/complex3.htm article …

Webbcalled imaginary and complex numbers. DefinitionofImaginaryNumbers: i2 = − 1(thus i = − 1 √) Examples of imaginary numbers include 3i, − 6i, 3 5 i and 3i 5 √. A complex number is one that contains both a real and imaginary part, such as 2+5i. With this definition, the square root of a negative number is no longer undefined.
