Finding real and imaginary roots
WebLearn about the imaginary unit i, about the imaginary numbers, and about square roots of negative numbers. In your study of mathematics, you may have noticed that some quadratic equations do not have any real number solutions. For example, try as you may, you will never be able to find a real number solution to the equation x^2=-1 x2 = −1. WebAug 6, 2024 · Real roots can be expressed as real numbers. Sometimes this is simple, as with #sqrt4=2#, sometimes a bit more complex and we approximate, as with #sqrt3=1.7320508....# But always we are working in real numbers. Imaginary roots are expressed in imaginary numbers, and the simplest imaginary number is #i=sqrt( …
