If we change the square + 2x-2 of the algebraic formula x into the form of square + k of (x + m), where m and K are constants, we can find the value of M + K

If we change the square + 2x-2 of the algebraic formula x into the form of square + k of (x + m), where m and K are constants, we can find the value of M + K


X squared + 2x-2 = x squared + 2x + 1-1-2 = (x + 1) squared-3
So m = 1, k = - 3
m+k=1-3=-2
The answer is negative 2



If the algebraic formula x2-3x + 2 is changed into the form of (x-m) 2 + K, where m and K are constants, then M + K=______ .


If x2-3x + 2 = x2-3x + 94-14 = (x-32) 2-14, M = 32, k = - 14, then M + k = 32-14 = 54



If x2-x-1 = 0, then X4 + 2x + 1 / x2=

Let x approach 0 and e ^ TaNx - e ^ X and x ^ n be of the same medium infinitesimal, then n =?


When x approaches 0, e ^ tanx-e ^ x is equivalent to tanx-x, and TaNx is equivalent to x + (1 / 3) * x ^ 3, so n = 3



How to do 3 (1 / 3) + 5 (2 / 4) + 7 (3 / 5) + 9 (4 / 6): 1 (2 / 3) + 2 (3 / 4) + 3 (4 / 5) + 4 (5 / 6)?


3 you (1 / 3) + 5 you (2 / 4) + 7 you (3 / 5) + 9 you (4 / 6) = 10 / 3 + 22 / 4 + 38 / 5 + 58 / 6 = 20 / 6 + 58 / 6 + 110 / 20 + 152 / 20 = 78 / 6 + 262 / 20 = 13 + 13.1 = 26.1 1 1 you (2 / 3) + 2 you (3 / 4) + 3 you (4 / 5) + 4 you (5 / 6) = 5 / 3 + 11 / 4 + 19 / 5 + 29 / 6 = 10 / 6 + 29 / 6 + 55 / 20 + 76 / 20 = 39 / 6 + 131 / 20 = 6.5 + 6.55 = 13.05, your adoption is my driving force,

A. B is two objects placed side by side close to the smooth horizontal ground, pushing a and B with horizontal forces F1 and F2. It is known that F1 = 10N, F2 = 6N, Ma is greater than MB,
What is the value range of the interaction force F between a and B?
F1 is the force acting to the right and F2 is the force acting to the left.


The results are as follows
The maximum total acceleration is Amax = (F1 + F2) / (MA + MB)
The minimum total acceleration is Amin = (F1-F2) / (MA + MB)
The maximum force is maamax = ma (F1 + F2) / (MA + MB), and the minimum force is mbamin = MB (F1-F2) / (MA + MB)



-What is the reciprocal of 1 / 3 + 1 / 4?
If a and B are opposite to each other and X and y are negative reciprocal to each other, then x + xy = ()


-The reciprocal of 1 / 3 + 1 / 4 is: 1 ÷ (- 1 / 3 + 1 / 4) = - 12
If a and B are opposite to each other and X and y are negative reciprocal to each other, then x + XY of (a + b) · y = (0)

The sum of the two primes is 31. What is the product of the multiplication of the two primes


The sum is even. For example, an odd even prime has only 2, so the other prime is 29 and the product is 58
