Why P Versus NP Can’t Work in All Instances

 See how [two variables form] a square? And see how the baseline [can be] lower on both for [a] lower percentage? That's showing the quadratic relation, since there are two variables. It's a quadratic expression. [A] doctor with [a] lower patient recovery [can] actually ha[ve] better results, in [two] cases. It's just what happens when you have two variables. Hence why Quadratic Equations make two answers. And coincidentally, why negatives turn positive when you multiply them together. It's all for the same reasons of logic.

Interestingly, on a cube, there's a negative and positive they cancel out, thus creating a zero variable--you can see that on the cubic equation.

And a quartic is just another kind of quadratic. 

But a quintic, there's no way we can solve some of them. As it's just too complicated of a geometric structure, there's only a few instances where we can solve those polynomials. So, if you're working in exponents of 5 or 7 or 11--basically primes or odd multiples of primes--or even fractional logarithms, you can have trouble solving for the polynomials. It's just the geometry of it is not possible. You have to break the equation down further, into geometry you can understand.
