Tet is a national and family festival. It is an occasion for every Vietnamese to have a good time while thinking about the last year and the next year. At Tet, spring fairs are organized, streets and public buildings are brightly decorated and almost all shops are crowded with people shopping for Tet. At home, every is tidied, special food is cooked,offerings of food, fresh water, flowers and betel are made on the family altar with burning joss- sks scenting the air. First-footing is made when the lucky visitor comes and children are given lucky money wrapped in a red tiny envelope. Tet is also a time for peace and love. During Tet, children often behave well and friends, relatives and neighbors give each other best wishes for the new year.

\(\frac{x+3}{x-2}=\frac{\left(x-2\right)+5}{x-2}=\frac{x-2}{x-2}+\frac{5}{x-2}=1+\frac{5}{x-2}\)
hàm số f(x) có giá trị ngyên \(\Leftrightarrow\) 5 \(⋮\)x-2
hay x-2 là các ước của 5
nên x-2\(\in\){-5;-1;1;5}
Vậy x\(\in\){-3;1;3;7}

để f(x) nguyên thì \(\dfrac{x+3}{x-2}\) nguyên
=> x+3 chia hết cho x-2
=> x-2+5 chia hết cho x-2
=> 5 chia hết cho x-2
=> x-2 thuộc : 1 ; -1 ; 5 ; -5
=> x thuộc : 3 ; 1 ; 7 ; -3

Our bodies are built of and powered by solely what we eat and drink. Food is the source of all of the energy needed Why do humans have to eat? Is it just because we get hungry? That is not all. People get energy from food. We need energy all the time, when we run, jump, sing, and even when we sleep. We create all the energy we need by eating. The structures components that make up the human body, such as muscles, organs, and bones, are also composed of the nutrients contained in food, meaning that it is. This is why eating and taking in the nutrients that provide energy and become the components of our bodily structures is essential to for sustaining human life.
