@dildare7663 3 года назад

My problem is that when I try to solve for the roots of an equation, i dont know which one to solve it with; the quadratic formula or completing the square? Then I try both of them for the same equation and get different answers. This is so frustrating.

@PegasusTenma1 3 года назад

Both can actually work, the quadratic formula is best for solving for irrational roots but if you wanted to, you could brute force it and use completing the square as well. It’s your choice.

I am really grateful to you for teaching all these concepts. I had learnt it in my college and now I'm required to teach these topics to some students, I am able to learn from you and then pass the knowledge to them. This is indeed really powerful what you are doing. By teaching me, you are actually teaching 3 others. And even with my knowledge refreshed, I will be able to convey it to more people. But, it is really feeling good to again understand all of these concepts. Thank you so much for all your help. By the way, I have even gone through many other videos from you for e.g. the Linear Equations which again I'm now confident to teach to my fellow pupils. Thank you brother for taking the effort to explain all of these concepts in such a easy way. At times, I will admit I had to repeatively watch few videos to learn but that is the way of learning. You have to go through a concept couple of times to completely understand. Liked, shared and subscribed!

In the last 2 it would be shorter and easier to divide all the terms by the coefficient of X^2 first, and then proceed from there. Ex. 3x^2 - 5x -7 = 0 --> x^2 -5/3x - 7/3 =0 --> x^2 -5/3x +5/6 =7/3 --> (x - 5/6)^2 = 7/3 + (5/6)^2 --> (x - 5/6)^2 = 7/3 + 25/36 --> (x-5/6)^2 = 109/36 --> Sqrt (x^2 -5/6)^2 = Sqrt (109/36) --> x^2 -5/6 = (sqrt109)/6 --> x = 5/6 +/- (sqrt 109)/6
