WebJul 3, 2024 · When dealing with fractions, if the numerator and denominator are the same, the fraction is equal to 1. Hence (1 – 3 j) / (1 – 3 j) = 1 Also, when a fraction is multiplied by 1, the fraction is unchanged. So we will multiply the complex fraction 2 / (1 + 3 j) by (1 – 3 j) / (1 – 3 j) where (1 – 3 j) is the complex conjugate of (1 + 3 j ).

First, and perhaps easiest, is to simply treat the fraction as a division problem and divide the numerator by the denominator. WebAgain, I can solve this in either of two ways. One way is to simplify by splitting up the sum and then simplifying each fraction separately: The other way is to simplify by taking the common factor of the numerator and denominator out front and then canceling it off: Either way, my answer is the same: 3 x2 − 5 x. how to stream on android
