What great influence did Peking University have on me?

The collection of more than 4 million books in Peking University has made me know my shallow knowledge, so that I can study selflessly. The brilliant and energetic students and the rigorous and sincere teachers in Peking University have made me feel the good teaching and learning style of Peking University, and thus become an excellent university student

What is the order of the article about the 13-year-old's fortune, and what kind of feelings he expressed for Peking University
The clearer, the better. Go to the troublemaker's side

Chronological order
According to the order of first meeting Peking University, first meeting Peking University and entering Peking University, the article expresses infinite gratitude and love for Peking University

If the value of fraction 2X-4 is positive, X should satisfy

(x²-4)/(2x-4)>0
(x-2)(x+2)/[2(x-2)]=(x+2)/2>0
have to
x+2>0 x>-2
x> - 2 and X ≠ 2

Given that the intersection of the vertex coordinates (- 2,4) and the Y-axis of the parabola is (0,3), find the analytic expression of this function

If the vertex coordinates (- 2,4), then y = a (x + 2) ^ 2 + 4
Substituting (0,3), 3 = 4A + 4, a = - 1 / 4
So y = - 1 / 4 * (x + 2) ^ 2 + 4

What is the approximate interval of the zero coordinates of the function f (x) = - x ^ 3-3x + 5?

It's a minus function, so there's a zero
f(1)>0
f(2)

9(x-1)

9x-9

To solve a simple quadratic equation of one variable
X & sup2; - 3x - 3 = 0, find the value of X

b^2-4ac=9-4*(-3)=21
X = (3 + radical 21) / 2
Or x = (3-radical 21) / 2

The fraction (5x ^ 2 + 12x + 29) / (2x ^ 3 + 10x ^ 2-3x-15) is decomposed into the sum of several partial fractions

There is a complete interpretation

X ^ 2-2x / 4 + X / 1 = X-2 / 2 solution equation

The two sides of the equation are multiplied by X (X-2) at the same time, and the unknown number in the denominator is removed. Then a one variable linear equation is obtained, and the solution is x = 2. But when x = 2, the denominator of the original equation is 0, so 2 is Zeng gen, so the original equation has no solution
