Solving equations over complex numbers
WebSep 16, 2024 · A real number only carries one piece of information: its location on the number line. So when you add two complex numbers, you need to keep track of the real parts and the imaginary parts separately. In your case, a + b = 4 and − 2 a − 3 b = − 6. So a = 6 and b = − 2. In most cases, it's actually better to think of complex numbers as ... WebSolve[a b I/(a + b I) == 4 - 2 I, {a, b},Reals]. Is there a simple way of getting Mathematica to solve this, without knowing lots of special Mathematica commands? In searching out the answer on this site, I see workarounds that a newbie to MMA would never think of themselves, nor understand what they are doing that gives the right answer.
