1.（a²+2ab+b²）÷a+b）=（a+b）²÷a+b）=（a+b）
2.（4a²-9b²）÷2a+3b）=[（2a）²-3b）²]2a+3b）=（2a-3b）
Calculation: If x -25 = 0, then the value of x is: 5 or (-5).
If x -3x = 0, then the value of x is: 0 or 3
If (x-2)(x+1)=0, then the value of x is: 2 or (-1).
If x+y=5, xy=3, then xy+xy=15; ②x²y+2x²y²+xy²= 33 .
Second, the calculation (the process is not used).
1）（6x²y+9xy²）÷3y+2x）=3xy
2）（4mn-m²-4n²）÷2n-m）=-（2n-m）
3）（a²xy-2abxy+b²xy）÷（a-b）=xy（a-b）
4）[（x²+y²）²4x²y²]÷x²-y²）=（x²-y²）
Third, solve the equation.
x = 36 x = 6 or x = -6
2x-1）²=25 |2x-1|=5, so x=3 or x=2
2x +7x=0 x=0 or x=-7 2
x -6x=-9 (x-3) =0 so x=3=-1
x+2) =(2x+1) x=1 or x
9(x+3) = (2x-5) x=-14 or x=-4 5
Here's a lesson exercise:
One. Compute. 2a³+6a）÷a=（2a²+6）
4m²+n²）÷2m+n）=（n-2m）
x -4x+4) (1-1 2x)=2x*(x-2) (2x-1) I don't know if you made a mistake in this question?
Two. Solve equations.
1.(2x-1)(x+3)=0 x=1 2 or x=-3
x=0 or x=-3 2
3.(2x+1) = (1-x) x=0 or x=-2
Three. Compute. （a-b）²+4ab]÷（a+b）=（a+b）
1-81x³）÷1+3x）÷（1+9x²）=（1-3x）
It's all simple deformations, and I hope you can learn it yourself.

1.After connecting a 50 resistor in series in a certain circuit, the current in the circuit becomes half of the original, then the resistance in the original circuit is 50 ohms If you want to make the current in the circuit become the original times, you need to connect a resistor in parallel in the circuit with a resistance value of 2 times the original. >>>More
Personally, as a mathematics student, I think that mathematics topics should not be just focused on one topic. The first is to master a method through practice questions, that is, to master the method in the early stage, and there can be several questions of the same method, and the method can be mastered through the questions. Then it is upgraded to a question type, that is, to see the characteristics of the question, and as soon as you see this kind of question, you can think of how and what kind of method. >>>More

If you want to take law as your future work direction, it is recommended that you take the college entrance examination and then apply for the law major in the university, orthodox legal education, the law learned in the university is very theoretical, can help you establish a systematic legal framework, which is very helpful for you to study law or engage in legal work in the future, and law is a very interesting subject, the more you learn, the more interested you will be. If you don't want to take this as a direction for future development, but just as a hobby, I think it's more difficult, because law is a broad and profound discipline, and it keeps pace with the times and changes all the time, even people who are engaged in legal work now have to study it every day, and I think it would be a burden to take it as a hobby. It is recommended that you take a look at the book "The Law of the West Window", which is a primer on law recommended by my teacher to students when I was in college, which are all short articles related to law, which can let you enter the door first, and can also provide materials for your high school Chinese composition. >>>More
