Thanks we were given to memorize these without proving and my silly brain thought it had be done by taking a common solution for the roots and continue from there. But that was not possible because deriving a common solution for cubics seemed a lot harder than quadratics. Yet, this method was easy to understand thank you!
Thank you for the video sir it was helpfull. But I think it's going to be better if you put videos vertically. We're waiting for new shorts sir. Greets from all way to Turkiye🇹🇷🇹🇷🇹🇷
@Truong, thank you so much for being active in your learning and for your kind comments. They are on my list as well, and I will cover them once I am done with Mathematics Advanced and Extension 1 topics.
I have answered the year 3 and 5 NAPLAN tests, and now I have to do the year 7 and 9 NAPLAN tests. You will be useful to my future exams and the present exams.🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉
