WebDec 8, 2015 · Use the FOIL method. (1 +i)(2 − 3i) = 1(2) −1(3i) +i(2) + i( − 3i) = 2 − 3i + 2i −3i2. = 2 − i − 3i2. While this may appear to be as simplified as possible, it's not. Since i = √−1, it's also true that i2 = − 1. Because of this, we can replace the i2 with −1. = 2 − i … WebA complex number is such that the absolute value of z = the absolute value of (z-3i) (a) Show that the imaginary part of z is 2/3. I tried squaring both sides and then I find by equating both sides, that when z = a + bi, b satisfies the equation: b^2 -7b +9 =0 however this does not give me b = 2/3.

WebVideo transcript. We're asked to add the complex number 5 plus 2i to the other complex number 3 minus 7i. And as we'll see, when we're adding complex numbers, you can only add the real parts to each other and you can only add the imaginary parts to each other. So let's add the real parts. So we have a 5 plus a 3. WebNo entanto, temos que: 3 2 = 3 e 4 2 = 4.
