Web(a+bi) (c+di) = (ac-bd) + (ad+bc)i For this product to be real, the imaginary part must be 0, so ad+bc = 0 As a and b are fixed, must have = . So, in general, for the product of two complex numbers to be real, the ratio of the real to imaginary parts of each complex number must be equal up to a minus sign. Or an imaginary number? Websum of two terms (each of which may be zero). The real term (not containing i) is called the real part and the coefficient of i is the imaginary part. Therefore the real part of 3+4i is 3 and the imaginary part is 4. A number is real when the coefficient of i is zero and is imaginary when the real part is zero.
