Như vậy, hai cây phong không chỉ là cảnh vật mà nó đã hóa thân như những người bạn thân thiết, gắn bó với ngôi làng, chứng kiến sự lớn lên của lũ trẻ.

Mình đã cố gắng làm đầy đủ

Chúc b học tốt

Tick dùm mk nha. Tks

b) x^3 + x^2 - 2x - 8 = 0

(x^3-8)+(x^2-2x)=0

(x-2)(x^2+2x+4)+x(x-2)=0

(x-2)(x^2+2x+4+x)=0

(x-2)(x^2+3x+4)=0

=>x-2=0 hoặc x^2+3x+4=0

x-2=0=>x=2

x^2+3x+4=0

x^2+2x.3/2+9/4-9/4+4=0

(x^2+2x.3/2+9/4)+(-9/4+4)=0

(x+3/2)^2+15/4=0

(x+3/2)^2=-15/4

Vì (x+3/2)^2>=0 mà-15/4<0 nên k tìm đc x thỏa mãn đk đề bài

Vậy x=2

Mình chỉ làm đc như này thui b thông cảm

Tick cho mình nha

a) ( x+2y)(x^2-2xy+4y^2)-8y^3+27=0

x^3+(2y)^3 - (2y)^3 + 3^3 = 0

x^3+3^3 = 0

(x+3)(x^2-3x+9)= 0

=> x+3=0 hoặc x^2 - 3x + 9 = 0

x+3 = 0 => x=-3

x^2-3x+9= 0=> x^2-2x.3/2+9/4-9/4+9=0

(x^2-2x.3/2+9/4)+(-9/4+9)=0

(x-3/2)^2 + 25/4=0

(x-3/2)^2 =-25/4

Vì (x-3/2)^2 >= 0 mà -25/4<0 nên k tìm đc x tỏa mãn đk đề bài

Vậy x=-3

To really understand a culture, you must speak the language. There is a trend to learn English all over the world now. It is true that English has become the international language of business, aviation and communication. Most leading countries in the world speak English . If we knowEnglish, we can communicate and read books in English. We can learn and understand more about the modern technology and sceince from these advanced countries. I think it is very useful for us to learn English well.
But how to learn English well? I have learned English for three years and I learned both at school and at home. At school, I will ask my teacher or my friends if I don't understand. At home , I often do more grammar exercises in grammar books or use Internet to search new excercises .
Besides, we can learn E by other ways. I always learn structures by heart and make sentences with structures. Now my writing and speaking is very good but my listening is bad. So I often speak e with my friends regularly, learn by heart all the new words, write E words as much as possible , watch TV programs, listen to E tapes or E programs on the radio, read short stories or newspapers in E, use a dictionary to look up new words,etc..
Nowsadays, E is acompulsory sencond language in many countries. That is my ways to learn E. I think we have different ways to learn well.

Both of us all know that English is an offical language in the world. Therefore, I think it is very useful and essential for us to learn English well.
But how to learn English well? I have learned English for three years and I learned both at school and at home. At school, I will ask my teacher or my friends if I don't understand. At home , I often do more grammar exercises in grammar books or use Internet to search new excercises .

Vì khi thêm vào số cam 126 quả và bớt số táo đi 60 quả thì số cam=số táo

=> số táo nhiều hơn số cam là:
126+60=186 ( quả)

Có số quả táo là:

(412+186):2=299 ( quả)

Có số quả cam là:
412-299=113 ( quả)

My favourite leisure activity is reading. I like reading because it is a hobby that is useful and interesting: useful because you can find a lot of knowledge of all areas that you need; interesting because the books can give you the joy and help you relax after a day of toil etc... Especially, when you join the forum, you can meet a lot of people who have interests similar to yours, comment on the books or novels that interest you.

I love books and also natural as reading books. At the age of ten, I was awarded "The Scarlet Sails" of Alexandre Green by my grandfather. It is the first of book that I have been. I read it does not know how many times (Up to now, I still love it and occasionally read it again). My love for books begun.

I usually spend almost of free time in choosing the book with my friends, participate in dicussion on the forum and reading (of course!). Every weekend and all holidays when I have no work to do, I often read books and ruminate on it. I also help some friends can select the genres of books that they like.

I always hope that I will have my own library in my future. I love books very much and perhaps, I couldn't live without them.
