Ta có: \(\left(x+2\right)\left(x^2+2x+2\right)-x\left(x-8\right)^2=\left(4x-3\right)\left(4x+3\right)\)
\(\Leftrightarrow x^3+2x^2+2x+2x^2+4x+4-x\left(x^2-16x+64\right)=16x^2-9\)
\(\Leftrightarrow x^3+4x^2+6x+4-x^3+16x^2-64x-16x^2+9=0\)
\(\Leftrightarrow4x^2-58x+13=0\)
\(\Leftrightarrow\left(2x\right)^2-2\cdot2x\cdot\frac{58}{4}+\frac{3364}{16}-\frac{789}{4}=0\)
\(\Leftrightarrow\left(2x-\frac{58}{4}\right)^2=\frac{789}{4}\)
\(\Leftrightarrow\left[{}\begin{matrix}2x-\frac{58}{4}=\frac{\sqrt{789}}{2}\\2x-\frac{58}{4}=-\frac{\sqrt{789}}{2}\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}2x=\frac{\sqrt{789}}{2}+\frac{58}{4}=\frac{29+\sqrt{789}}{2}\\2x=-\frac{\sqrt{789}}{2}+\frac{58}{4}=\frac{29-\sqrt{789}}{2}\end{matrix}\right.\)
\(\Leftrightarrow\left[{}\begin{matrix}x=\frac{29+\sqrt{789}}{4}\\x=\frac{29-\sqrt{789}}{4}\end{matrix}\right.\)
Vậy: \(x\in\left\{\frac{29+\sqrt{789}}{4};\frac{29-\sqrt{789}}{4}\right\}\)

In order to stay healthy it is important to have a balanced diet. We should eat enough three main groups of food. These groups are protein, carbohydrate and fat.
Proteins are very important for building our body. They help us to build new cells as old ones die. Meat and milk products are major sources of protein. We can also get protein from fish, eggs and beans.
Carbohydrate and fat are important to enable us to store energy. Carbohydrates are found in sugar and in cereals. Fat can be found in vegetable oil, in butter and in nuts.
Our body also needs minerals, such as iron and calcium and vitamins. Fish, vegetables and milk contain most of the minerals we need. Vitamins are found in fresh vegetables and fruit.

1. I think diet is important for vegetarians or somebody who wants to lose their weight.
2. A balanced diet is the menu of vegetables, fruits, healthy dish and there is no fish, meat or something related to animals that provides our bodies with all the vitamins and nutrients.
3. In my country, they often eat a lot of vegetables and fruits in three big meals in a day. Some people is very healthy because they do the diet everyday, but some other people are the complete opposite of them, like me, for example, if I can't eat meat or fish for a day...... Oh, it is so scary! :)
4. Yes, they do. For example, in Hanoi, we prefer eating at home to going out, but in Ho Chi Minh city, they always go out to have breakfast, lunch, dinner and sometimes I read on my aunt's Facebook, they post a photo with the title:" How to fry the eggs?" or " My dark meal :((("
5. I think it's more convinient for everybody and if you want to "change the wind", let's go out now! Of course it is more expensive but it's worth, right?
This is my opinions, it may be wrong. I'll be very pleasure for your comments
Thanks for reading and have a good day, :)))))

I think diet is important for us because focusing on that would make us healthy. In my opinion, balanced diet is that you eat each type of food just enough, no more or less. For instance, you have to eat meat less than fruits and vegetables. Most of Vietnamese people have rice for there diet, and lots of people prefer to have canned food. Many people enjoy eating out when they busy and don not have time to make their own food and the food might be better. I think the most different between restaurant food and cooked food is that the food in restaurants is usually better than cooked food.

1.I think yes because the diet is quite important because it affects both our weight and our body.
2.A balanced diet is the right diet that provides our bodies with all the vitamins and nutrients it needs to function properly.
3.They often eat a lot of vegetables for breakfast, lunch, dinner and in between snacks they often eat fruit.
4.Some people like to eat out because they don't have enough time to prepare their meals, they like to eat out because they are attracted to them, delicious food.
5.The difference is that the food outside the restaurant can't be 100% sure that they are good for health and ensure proper food safety and hygiene or how to prepare food, where the source of that food is unknown. As for home-made food, we make sure that the place where we buy food is a hygienic place, the way we prepare food in accordance with hygienic regulations and that the food is good for health.
Is very important to having a balanced diet.
