That's funny! Thanks for the comment.

[@arjanbaraku6281]

Sir I didn’t understand how you put -9 lambda and + lambda square in 3:50

[@MichelvanBiezen]

We multiplied ( 2 - lambda) (7 - lambda) = 14 - 9 lambda + lambda^2

[@matthings4133]

Shouldn't it technically be - 0 in the first equation because of the alternation of the (-1)^n?

[@MichelvanBiezen]

+ 0 = - 0

Good video, nice work! That really help me.

Muchas gracias por su video me ayudo un monton para una prueba

You are welcome. Glad you found our videos. 🙂

Seriously thank you soo much very helpful 😎👌

you should set up a patreon!

[@bigbossyair]

hello , how you can resolve the same situation, but whit a 4x4 matrix? thanks so much for teach me...

[@MichelvanBiezen]

It would be exactly the same, except the algebra of finding the roots would be harder.

[@kachiya8571]

Sir plz solve cube power of lemda immediately

[@fishfish1051]

Thank you for your video, it helps me a lot❤️ a student from hk ☺️

Welcome to the channel!

[@joseemmanuelnavarro7210]

Very Useful! do you have 5x5? based on other examples 5x5 would be very tedious.

[@MichelvanBiezen]

The only difference is time. It would take a very long time to work out a 5 x 5.

@@MichelvanBiezen Thank you! sir, I end up using Online calculator hehe I'll be using this for dynamic analysis in structures.

Thanks sir I really need this 😊😊😊

Thank you! Very helpful!

Sir lambda^3-7lambda^2+2lambda+64 please solve it

[@MichelvanBiezen]

I tried some quick calculations using synthetic division, but I didn't see any obvious integer roots.

Wow lo explico super bien y eso que no entiendo ingles

Gracias

[@GHULMILTUBE6798]

You mistaken middle -3 there you write +3 cheak sir reply m fast

[@MichelvanBiezen]

The video is correct. Thanks for checking. (both sides of the equation were multiplied by a "-1" )

[@GHULMILTUBE6798]

@@MichelvanBiezen ok -1- lemda convert to +1+lemda you r write sir ginius love your trick sir thank 👍😊
