01 - Solving Equations in Quadratic Form - Part 1 (Learn to Solve Equations in Algebra)

In this lesson, you will learn what it means for an equation to be represented in "quadratic form". This means that the equation has the general form of a quadratic function, but the variables may be slightly more complex expressions.
To solve these types of equations, we first perform a substitution where we let the variable "z" represent a part of the equation. The result of this is a classic quadratic equation in "z" that can then be solved and represented in terms of the original variable "x".

He has a great way of teaching. He's to the point but with an explanation that most can grasp. I know I'll be ordering a few lessons from him.

He is good teacher / lecturer he like to emphasize a particular subject which most teacher hardly to explain. His ambition technic encourages to one focus. I am very excited. Love him.
You're the best teacher I've ever come across... Not tryna fool you or anything.. I mean it😭
I learned so much from his classes:very hypnotic and keeps one engaged.
Tutorial starts at 4:30

Your welcome!
hey, really nice video I never knew this technique existed, I see the premise of what youve taught is breaking it down into quadratic form but one quick lil doubt, at 32:27 in the video the square root of 1 is -1 cuz -1 x -1 = 1. What you meant was if x^2 = -1, thats not possible but square root of x = -1 is possible, atleast I think sooooo....
The math is really nice, and I hope we can connect it to the world of mathematics

Its already connected. Math and math.
This teacher is the best teaching
Amazing explanation
Best Video. Thanks!
Great! Thx, from Brasil!
When the solutiom is on the y-axis, is it open or closed?
Hey, pls I don't really understand the substitution method, I don't know if there's a topic before this one that has more detailed explanation about substitution than this, thank you
sqrt(i^4)=-1, no? It appears to work in the equation, too.
In the examples of quadratic equations, the 3rd equation when x=o, the function is undefined. So it can’t be a quadratic equation, is it?
Really want to order but I can't afford to renew every month so any advice
Well done teacher ❤❤❤
your teaching is amazing?
Ngl I wish I had him as my teacher

You do. U js gotta watch the video.
Thank you 🙏
Coincidentally I was trying to fit a parabola through three points today. Initially I used a sigmoid function and could successfully calculate parameters to fit it through two points and could move the remaining parameters by hand to make it go through the third, but for the life of me can't solve the parameter for the third point mathematically. Hence I tried a parabola instead and ran into the same problem. Am I missing something or is this just not that trivial?
Best teacher in the world

The other reason there is only one true solution is that the highest power is one. So it still follows the rule that the number of solutions will be the value of the highest power.
Good day how can I aquire full coarse thanks

I don't understand why not root of x is equal to -1 is answer of the problem
I think,square root of any expression equated to a negative number has no solution.
What grade do you learn this in 9th-11th..? (That’s what google told me 😭

i love you, don't know why but i just do
I don’t think you solve the problem. Just you substation. I was waiting to solve the quadratic question. you just substitute.
