The function f (x) holds for all real numbers x and y, f (x + y) - f (y) = x (x + 2Y + 1), and f (1) = 0. (1) find the value of F (0); try to determine the analytic formula of function f (x)
Answer to the detailed process and analysis, thank you

(1) Let x = 1, y = 0
F (1) - f (0) = 2, from F (1) = 0: F (0) = - 2
(2) Let y = 0
F (x) - f (0) = x (x + 1), so f (x) = x (x + 1) - 2

As shown in the figure, in rtabc, ACB = 90 ° CD ⊥ AB in D de ⊥ AC in E DF ⊥ BC in F, AE × BF × AB = CD cubic
As shown in the figure, in rtabc, ACB = 90 ° CD ⊥ AB in D de ⊥ AC in E DF ⊥ BC in F, AE × BF × AB = CD cubic

It is proved that: ∵ - a = ∵ BCD (all are the remainder of angle b); - AED = ∵ CDB = 90 degrees. ∵ ⊙ AED ∵ CDB, CD / AE = BC / AD; - --- (1) similarly, it is proved that: ⊙ ADC ∵ DFB, CD / BF = ad / DF; - --- (2) ⊙ CFD ∵ ACB, CD / AB = DF / BC

Square of AX + BX + C = 0 (square of B - 4ac > 0)
It can be solved by matching method
Hurry up, please

ax²＋bx＋c＝0 x²＋b/a x＋c/a＝0 x²＋b/a x＋﹙b/2a﹚²＝﹙b/2a﹚²－c/a ﹙x＋b/2a﹚²＝﹙b²－4ac﹚/4a² ∵ b²－4ac＞0 ∴ x＋b/2a＝±√﹙b²－4ac...

What's the difference between could you please tell me your name? And could you tell me your name, please?

The former is more polite than the latter

After adding 3cm to the two adjacent sides of a square, we get a new square. The area of the new square is 39 square centimeters larger than that of the original square. What's the area of the original square?

Let the side length of the original square be x cm. According to the meaning of the question, we can get: 3x + 3x + 3 × 3 = 39 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 6x + 9 = 39 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 6x = 30 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 5 the area of the original square: 5 × 5 = 25 (square centimeter) a: the area of the original square is 25 square centimeter

Can Chinese explain a word only with synonyms and antonyms? But now others say it is synonyms and antonyms. Which one is better?
What to do? One is synonym and antonym, two is synonym and antonym
Is there a difference between synonyms and near synonyms?

Synonyms and synonyms refer to the same scope. They both refer to words with the same or similar meaning. Therefore, the two explanations are the same. When a language discipline interprets a word, the first thing to explain is the basic meaning of the word. If it wants to be more complicated, it should also explain the extended meaning of the word, that is, the meaning derived later
