@@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

X x X + (3x3xXxX) - - - - - - - - - = 16 (XxX-3x3) > the Xs and 3s in the bracket crosses out. X x X = 16 X squared = 16 Now, remove the squared from the X, but to do that you have to put 16 in square root sign X = square root of 16 X = 4.
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 $x^{2}+(\frac {3x}{x-3})^{2}=16$.

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
Yet another method is to note that (x − 3)² = x² − 6x + 9 and therefore x² = (x − 3)² + 6x − 9 so we can rewrite the equation x² + (3x/(x − 3))² = 16 as (x − 3)² + 6x − 9 + (3x/(x − 3))² = 16 or (x − 3)² + 6x + (3x/(x − 3))² − 25 = 0 Here (x − 3)² + 6x + (3x/(x − 3))² is a perfect square because 6x is twice the product of (x − 3) and 3x/(x − 3) and we also have 25 = 5² so we get ((x − 3) + 3x/(x − 3))² − 5² = 0 which gives us a difference of two squares at the left hand side whereas the right hand side is zero. This allows us to factor the left hand side using the difference of two squares identity and then apply the zero product property. However, before doing so we first multiply both sides by (x − 3)² to eliminate the fraction so we get ((x − 3)² + 3x)² − (5(x − 3))² = 0 (x² − 3x + 9)² − (5x − 15)² = 0 (x² + 2x − 6)(x² − 8x + 24) = 0 x = −1 + √7 ⋁ x = −1 − √7 ⋁ x = 4 + 2i√2 ⋁ x = 4 − 2i√2
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.

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 ❤❤❤

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
Excellent. Straight to the solutions. Well done!

Thank you. very nice solved equation.
Как прекрасен язык математики. Всё понятно, подробно объясняно. Учитель супер. Спасибо за ролик.
I prefer to take the square root first and then expand with x-3. This is faster.
X x X + (3x3xXxX)
- - - - - - - - - = 16
(XxX-3x3)
> the Xs and 3s in the bracket crosses out.
X x X = 16
X squared = 16
Now, remove the squared from the X, but to do that you have to put 16 in square root sign
X = square root of 16
X = 4.
In fact I wonder how in this life am I going to use all this effort to solve my problems 🤷🏿♂️😂😂😂
Binomial triangle can solve the equation in just few lines . You like extra sheet
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.

what about if you can make both side in square root and find the value of x=12 andx=4
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
The secret to solving the equation is formulating it into a product of two quadratic expressions that gives zero

Yet another method is to note that (x − 3)² = x² − 6x + 9 and therefore x² = (x − 3)² + 6x − 9 so we can rewrite the equation
x² + (3x/(x − 3))² = 16
as
(x − 3)² + 6x − 9 + (3x/(x − 3))² = 16
or
(x − 3)² + 6x + (3x/(x − 3))² − 25 = 0
Here (x − 3)² + 6x + (3x/(x − 3))² is a perfect square because 6x is twice the product of (x − 3) and 3x/(x − 3) and we also have 25 = 5² so we get
((x − 3) + 3x/(x − 3))² − 5² = 0

((x − 3)² + 3x)² − (5(x − 3))² = 0
(x² − 3x + 9)² − (5x − 15)² = 0
