@nextdoortutor b^2 -64 must be a perfect square. So b is the hypotenuse of all Pythagorean triplets with one side equal 8. So the answer is 6. I will make a video on this.
I would like to see explanation of algorithm which can be found in Knuths book Application of matrix inverse is solving systems of linear equations . We probably will see soon more about row operations row echelon forms ,linear combination,linear dependence of the vectors, rank of the matrix

i haven't even start watching the video but seeing that its you makes me happy knowing that it would be broken down to the lowest level. Thank You
You make stressfull math, sounds like just another calm day in the park.
Thanks for your video, it helped me a lot!

Thank you very much for your help 🎉 it's so much easier. You're an awesome guy and teacher! 🎉
Happy to help!
I love your videos! Can you please upload more AMATYC competition questions please! I am currently a student, and I am inspired by the way you teach.
Please send me AMATYC problems you find interesting, and I will make videos for them.
For how many different integers b is the polynomial x^2 +bx + 16 factorable over the integers? Thanks!
