Cardanno' method of solving cubic equation

Hello everyone . I am a 10th class student.Recently while surfing the net I found a method called the Cardanno's method of solving cubic equation. So ‚ I started to search for the same and found lot of stuff .But the explanation was too complicated.So if someone could show some examples for the same then I could stop scratching my head and scribbling on my notebooks (I want examples of all the 3 possibilities of roots i.e all real or all complex )

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Hi , I have learnt Cardano's method from here , I hope it will suffice . Also, in a few days time I am planning to write up a wiki on it .
