I enjoyed your work and your explanation. Excellent and well done! These problems can be long and it took nearly three pages for this one! Lol Sometimes it feels like you're going down a math rabbit hole with no end but in the end when you do reach a solution (s) it's all good.

@@DanielDimov358 If you have two quantities a and b then their average is ½(a + b). Since a and b are equidistant from their own average, you can get the original quantities back by adding half their difference ½(a − b) to their average and by subtracting half their difference from their average. That is, we have a = ½(a + b) + ½(a − b) b = ½(a + b) − ½(a − b) The average of x² and x² − 6x + 18 is half their sum, which is x² − 3x + 9 = x² − 3(x − 3) and their difference is x² − (x² − 6x + 18) = 6x − 18 = 6(x − 3) so half their difference is 3(x − 3). Therefore, we have x² = x² − 3(x − 3) + 3(x − 3) and x² − 6x + 18 = x² − 3(x − 3) − 3(x − 3) Consequently, the product x²(x² − 6x + 18) can be written as (x² − 3(x − 3) + 3(x − 3))(x² − 3(x − 3) − 3(x − 3)) and applying the difference of two squares identity (a + b)(a − b) = a² − b² this gives (x² − 3(x − 3))² − 9(x − 3)² or (x² − 3x + 9)² − 9(x − 3)²
Não acredito que o melhor professor do mundo tenha uma visão de primeira, para saber que o caminho é este aplicado nesta questão.(I don't believe that the best teacher in the world has the first-class vision to know which way is applied to this issue.)
The correct answer is: $x = 0$ Explanation: In the previous responses, we found that the equation $x^{2}+(\frac {3x}{x-3})^{2}=16$ has only one solution, which is $x = 0$. This is because when we substitute $x = 0$ into the equation, both terms on the left-hand side become zero, resulting in the equation being satisfied. Therefore, $x = 0$ is the only value of x that satisfies the equation $x^{2}+(\frac {3x}{x-3})^{2}=16$.
Never ending marathon mathematics and brain 🧠 puzzled stories ever. Einstein newton and all superb mathematicians brain to be needed to understood not like me the stupid one..not getting any sweet juice extract from your mathematics, all energies i have lost to get it understood sir .really sir you've the genius brain and you're great.❤❤❤after this life i shall pray to God ,make me genius like you.❤❤❤❤❤

Too long explanation and you should have switched to the quadratic equasion earlier, it was inevitable and as far as I know there is no negative square root, because any negative number squared gives a positive number, and a positive number squared is anyway positive
If I watched a few videos like this, I would be mentally ill. 😂😂😂
Me and you my friend, me and you!
And the biggest question is when is this used in the real world?😅😅😅

x^2 + (3x/x-3)^2 = 16
x^2 = 16 - (3x/x-3)^2
x^2 = 4^2 - (3x/x-3)^2
(4^2 - (3x/x-3)^2 - difference of squares)
x^2 = (4 - (3x/x-3))(4 + (3x/x-3))
After simplifying the expressions in the parentheses...
x^2 = (x-12/x - 3)(7x - 12/x - 3)
Using polynomial division...
x^2 = (1 - (9/x-3))(7 + (9/x-3))
Then let 9/x - 3 = a
From this we can express the x = (9 + 3a)/a
And we can substitute in the equation to get...
((9 + 3a)/a)^2 = (1 - a)(7 + a)
(9 + 3a)^2/a^2 = -a^2 - 6a + 7
(9 + 3a)^2 = a^2(-a^2 - 6a + 7)
Expanding the parentheses we get...
9a^2 + 54a + 81 = -a^4 - 6a^3 + 7a^2
a^4 + 6a^3 + 2a^2 + 54a + 81 = 0
a^4 + 8a^3 - 2a^3 + 9a^2 + 9a^2 - 16a^2 + 72a - 18a + 81 = 0
a^4 + 8a^3 - 9a^2 - 2a^3 - 16a^2 - 18a + 9a^2 + 72a + 81 = 0
a^2(a^2 + 8a + 9) - 2a(a^2 + 8a + 9) + 9(a^2 + 8a + 9) = 0
(a^2 + 8a + 9)(a^2 - 2a + 9) = 0
Roots of first equation are:
a1 = -4 + √7
a2 = -4 - √7
Roots of second equation are:
a3 = 1 + 2√2i
a4 = 1 - 2√2i
Using the roots of the first equation...
x = 9 + 3(-1 + √7)/-4 + √7 = -1 - √7
x = 9 + 3(-1 - √7)/-4 - √7 = -1 + √7
...after multiplying by the conjugate.
Very long and unnecessary I know, however it is the way I solved it and I wanted to share it.

I did this kind of maths about 40 years ago. Thanks for the reminder son.
Please always make your solution simple, to the subject interesting to all, first clear the squares and solve within a minute
Nice solution specially how got the (x-3) out of 6x^3+18x^2, neat trick.

I prefer to get rid of fraction first, then solution will be of 2 minutes only
Would have been way faster and easier. So much less time to multiply through then gather terms.
Yes,I agree

The solution become.complicated,rather than simplfied😮
It's a troubled solution.
Kafa ütülemek matematiği hiç sevmem
Binomial triangle can solve the equation in just few lines . You like extra sheet
A different approach which does not require a substitution and which does not require having to deal with fractions starts by multiplying both sides by (x − 3)² to get rid of the fraction. We can then proceed as follows
x²(x − 3)² + 9x² = 16(x − 3)²
x²(x² − 6x + 9) + 9x² = 16(x − 3)²
x²(x² − 6x + 18) = 16(x − 3)²
(x² − 3(x − 3) + 3(x − 3))(x² − 3(x − 3) − 3(x − 3)) = 16(x − 3)²
(x² − 3x + 9)² − 9(x − 3)² = 16(x − 3)²
(x² − 3x + 9)² − 25(x − 3)² = 0
(x² − 3x + 9 + 5(x − 3))(x² − 3x + 9 − 5(x − 3)) = 0
(x² + 2x − 6)(x² − 8x + 24) = 0
x = −1 + √7 ⋁ x = −1 − √7 ⋁ x = 4 + 2i√2 ⋁ x = 4 − 2i√2
I would have done same 👍🏻
You're also a great genius ❤❤❤
More simpler
Where does line №4 come from?
@@DanielDimov358 If you have two quantities a and b then their average is ½(a + b). Since a and b are equidistant from their own average, you can get the original quantities back by adding half their difference ½(a − b) to their average and by subtracting half their difference from their average. That is, we have
a = ½(a + b) + ½(a − b)
b = ½(a + b) − ½(a − b)
The average of x² and x² − 6x + 18 is half their sum, which is x² − 3x + 9 = x² − 3(x − 3) and their difference is x² − (x² − 6x + 18) = 6x − 18 = 6(x − 3) so half their difference is 3(x − 3). Therefore, we have
x² = x² − 3(x − 3) + 3(x − 3)
and
x² − 6x + 18 = x² − 3(x − 3) − 3(x − 3)
Consequently, the product x²(x² − 6x + 18) can be written as
(x² − 3(x − 3) + 3(x − 3))(x² − 3(x − 3) − 3(x − 3))
and applying the difference of two squares identity (a + b)(a − b) = a² − b² this gives
(x² − 3(x − 3))² − 9(x − 3)²
or
(x² − 3x + 9)² − 9(x − 3)²
Yeeeeee my brain already bursted🤣🤣🤣
😂
How did you know😮
I prefer to take the square root first and then expand with x-3. This is faster.
too long solution that's why many of us ignored Maths . From your side, excellent potential !
Please give a sense to those x and numbers. Be realistic. Don't speak in signs. Unless you are hiding something.
Excellent. Straight to the solutions. Well done!

This is crazy!
Clumsy solution. You try to over complicate the solution.
Too long way and time
Good evening ma. Pls i need help in advance level math and physics pls.
The ưay you solve this equation sis SO LONG.
Pourquoi tu nous dis que racine carré de I est égal encore à i? Ça n'a pas de sens. Il y a un problème avec le résultat à la fin
That is also how learning german will treat you as bigginer.
All these hours, just only to find X 😂

I really like his explainations! 10 of 10 again. Thank you!
Im not a verygood mathematecians. But i know how to solve problems.in algebra.and calculus.
No wonder I was failing maths
Did the teacher seriously expect me to memorise all this 😳
It can be solved by converting x to a trigonometric function.
(x/4)^2 + (3x/(4(x-3)))^2 = 1
x/4 = cos
3x/(4(x-3)) = sin
16(cs)^2 - 18cs - 9 = 0
Why does algebra have such complications and confusing sequence to solve the problem?😂😂
Hope this can be useful in real life
😂😂😂

So the underroot of negative one is i, how about the underroot of another negative number?
Thank you. very nice solved equation.
The secret to solving the equation is formulating it into a product of two quadratic expressions that gives zero
Too long way method.
