What are a and b in a²+2ab-39=0? Blank before rewriting...! ?

Hello. This is Nada from Seito Medical School. Today I would like to disclose top secret information written in my diary notes. Let's start with the first part. It's the first half. I would like to introduce the second half of the second round in the next article.

“ The Economics of Chest Deposits! ``Nobel Prize for supplying corporate internal reserves to the market '

' - Rewriting this article to medical school.

Conclusion. With my current knowledge of economics, there are too many blanks to rewrite. He also resumed studying economics.

a²+2ab-39=0 means 39=3×13, so a=3, 13 is the answer.

3²+2x3b=39b

=5

13²+2x13b=39

169+26b=39b

=-5

My challenges with shogi are: (1) It's quite easy to get caught in the final stages, (2) the players around the king become sparse because they don't solidify their defense in the early stages, and (3) I have to be conscious of filling in the outer moat in local games. There are three points. It looks like it's going well in the beginning, so I'd like to see some sharp shogi towards the end.

The longer you sleep, the more you want to sleep. Get through it with 5-6 hours of sleep! My assumption is that the busier people are, the slower they age. Of course, what you eat is important, but as I wrote above, oil, alcohol, and salt may be the natural enemies of youth. It would be fun to conduct research on how the appearance of busy people changes compared to non-busy people.

Writing down sentences in a single notebook is a very difficult task. In the old days, people didn't have printing machines, so he copied them into his own notebook. I thought that was amazing. A long time ago, books were expensive because they had to be copied by hand, but now you can buy them for 2,000 to 3,000 yen, so it feels like a waste not to buy them.
