Just multiply both sides by the sum of the roots of 14 and 13 and also by the sum of the roots of 13 and 12, and the answer is pretty obvious.

You know there are 3 roots. It's obvious that one is 2 at an angle of zero. The others are equidistant around a circle in the real/imaginary plane. 360/3=120 degrees apart. solve for sine and cosine to get the imaginary and real parts.

Nice content I really enjoyed it

You could also write 1 as log10 then Write Log[2x^2 -1] = log[10(1/2-x/10)] Then 2x^2-1=5-x And then solve for x

I am from India 🇮🇳 you make nice video

Very nice explanation 🎉

2:28 Wouldn't you go by the order of operations by adding first? Like m - (m + m) = 1 and (m + - m) - (-m) = -m?

"That's a gay question with a gay answer" - not my math teacher

easy. Multiple either part of the LHS by its conjugate. Then solve the binomial. Take the log of both sides and divide. x = +/- 2.

Thanks so much it was clearly explained 🙏🙏

Nice background

15 minutes is not the same as 15 seconds. Here goes, what is average IQ?

why is that x sign 3?

it’s so easy, isn’t it?

i though we would use log func

This is the easiest math in grade 6 in Viet Nam

Nice! Love it!❤

So smart …

❌

You can automatically solve it when it is x^3-2^3 and you get x is 2

I like short and quick solutions

Why can’t he just bring the eight across to get x^3 = 8 and cube root both sides?

The roots of this equation are incredibly symetrical. Writing x=e^(iy) yields all 3 solutions almost immediately, and exposes the cool symmetry which one otherwise misses.

How abeg😂

Nice job

Nice. So many videos similar to this neglect the imaginary solutions

This is ridiculous

try x^x = 10

❤❤

like browns do mathematics hahaaaaaaaa

The square root of 2 isn't 1... That's the first mistake in this video, which makes the rest of the video useless... The square root of 2 is 1.414, so your math is broken

Please do 1 ∫ ln(1−x)/x dx 0

This is a lie. There is no way this is an olympic question. Even avarage high school kids can solve this in Turkey.

it was fun and useful, thank you

My dumb ass would have tried w lambert function and fail miserably

Good job 🎉

nice ! and well explained 👌✨

Sir how will I realise that the + m needs to be split as -4m and +5m ?

Underrated ❤

Thank you

Very helpful, thank you!

Nice Solution but honestly why put the tetration? You could just use m^m this is just irritatingfor people who dont know the tatration notation and also kind of clickbaity

so x and y are not real numbers?

Impossible

You are being fooled with this nonsense! This method only works if you know the solution in advance. You need to split a number like 30 into two numbers x and y, such that x + y = 30 and 3^x = y (ie. 3 +27 = 30 and 3^x = 27), where x must be the solution you are trying to calculate. In other words, you need the solution of the problem in order to successfully follow the last steps. For example, if you try to solve 3^x + x = 40, you just need to split 40 into 3.279887… (the solution to the exercise!) and 36.72011..., both irrational numbers (infinite decimals), since 3.279887… + 36.72011... = 40 and 3^3.279887… = 36.72011... Brilliant method!

I don't know how but I solved it 😮 🇮🇳

Answer :- x(5x+1)

This is a grammar question not a math question for which it has no answer. You generated an algebra equation from your interpretation of the question for which you correctly solved but it still doesn’t tell us how much the pen really is. Poorly worded and ultimately not real world practical.
