Witryna15 cze 2012 · If the discriminant is negative, the square root of the discriminant will produce imaginary roots, which we can't plot. Conversely, if the discriminat is positive, you will have real number roots and you'll be able to plot them onto the screen. ... (As you can see, "imaginary roots" means, for our purposes, that the curve doesn't ever … Witryna17 lip 2024 · Solution. a + b i. Remember that a complex number has the form a + b i. You need to figure out what a and b need to be. a − 3 i. Since − 3 i is an imaginary number, it is the imaginary part ( b i) of the complex number a + b i. This imaginary number has no real parts, so the value of a is 0. 0 − 3 i.
