It's necessary to keep your fit. There are many way for you keep your fit. But I think you can notice some point. First, you should do exercises regular such as swimming, jogging, or ride bicycle. The second, you should have a good diet, eat enough the nutriment and usually have breakfast. You should eat less meat, more and more vegetable, fruit, salad, and drink a lot of water, about 1,5l to 2l per day. Next, you should go to bed early, not stay at late, and at least 6 hours per day. And finally, you shouldn't work too hard, reduce the pressure and stress. That is many way to keep your fit, you can do it.

Bài 6

a) (3x² + 5) + [(2x² - 5x) - (5x² + 4)]

= 3x² + 5 + (2x² - 5x - 5x² - 4)

= 3x² + 5 + 2x² - 5x - 5x² - 4

= (3x² + 2x² - 5x²) - 5x + (5 - 4)

= -5x + 1

---------‐----------

b) (x + 2)(x² - 2x + 4)

= x.x² - x.2x + x.4 + 2.x² - 2.2x + 2.4

= x³ - 2x² + 4x + 2x² - 4x + 8

= x³ + (-2x² + 2x²) + (4x - 4x) + 8

= x³ + 8

-------------------

c) (4x³ - 8x² + 13x - 5) : (2x - 1)

= (4x³ - 2x² - 6x² + 3x + 10x - 5) : (2x - 1)

= [(4x³ - 2x²) - (6x² - 3x) + (10x - 5)] : (2x - 1)

= [2x²(2x - 1) - 3x(2x - 1) + 5(2x - 1)] : (2x - 1)

= (2x - 1)(2x² - 3x + 5) : (2x - 1)

= 2x² - 3x + 5
