My house in the future will be a candy house. It is a big house with syrup and fruit juice covering my house. In front of the house there will be a robot made of cakes, and welcome me very intimately when I return home. The house is decorated with 2 big candy trees. On top of the house there are chimneys and my house is surrounded by big trees. In my house there are 4 rooms: 1 living room, 2 bedrooms and a kitchen. My robots will do all the housework to help me. In the living room, there will be a table and many sofas. It will have a hi-tech TV, I can watch many different programmes. In the kitchen, there will be a stove, a fridge, a microwave. In each bedroom, there will be a king-size bed, an air-conditioner, some pillows, some blankets. I love my future house and I wish it will come true someday.

\(\frac{5}{x^2-2x+2}-\frac{8}{x^2-3x+5}=3\)ĐKXĐ : ko biết >: delta toàn <0 thôi.

\(\frac{5\left(x^2-3x+5\right)}{\left(x^2-2x+2\right)\left(x^2-3x+5\right)}-\frac{8\left(x^2-2x+2\right)}{\left(x^2-3x+5\right)\left(x^2-2x+2\right)}=\frac{3\left(x^2-3x+5\right)\left(x^2-2x+2\right)}{\left(x^2-3x+5\right)\left(x^2-2x+2\right)}\)

Khử mẫu ta đc : \(5x^2-15x+25-8x^2-16x+16=3x^4-15x^3+39x^2-48x+30\)

Mời chế giải nốt ... con sợ dài rồi.
