It is known that x square x 8 6 x 9 x m x 3 3 m x n 2 2 is found to be the value of M N

m/(x+3)+n/(x-2)=[m(x-2)+n(x+3)]/[(x+3)(x-2)]= [mx-2m+nx+3n]/[x2

x-6]=[(m+n)x+(3n-2m)] [x2x-6]known(8x+9) (x2

x-6)=[(m+n)x+(3n-2m)] [x2x-6], so.

m+n=8 ①

3n-2m=9 ②

To solve the equation, 2+ gives 2n+3n=8 2+9, 5n=25, n=5 substituting m=8-n=3

x + m of 3/3 + x - n of 2/2

So m(x-2)+n(x+3)=8x+9;

So m+n=8;

3n-2m=9；

5n=25；

n=5；m=3；

Equal according to the corresponding coefficient.

m+n=83n-2m=9

So m=3, n=5

Summary. Hello, 1/3 x (-3) of 2 square + 9/9 x 18-3x6 + (-1) of 5 square x7, the specific calculation process is as follows:

1/3 x (-3) of 2 squares + 9/9 x 18-3x6 + (-1) of 5 square x 7

Hello, 1/3 x (-3) of 2 square + 9/9 x 18-3x6 + (-1) of 5 square x7, the specific calculation process is as follows:

Are you there. What the hell is the question?

I sent you, 2 questions.

Are you there. That's it for the whole calculation.

(4/3) x-m = (8/7) x-1

4/3) x - (8/7) x = 1+m

4/21) x = 1+m

x=( 1+m) (4/21).

x=(－21+21m)÷4

x＜0(－21+21m)÷4＜0

21+21m＜0

21m＜21

m 1 so m max is 1

4x/3-m=8x/7-1

4x/21=m-1

In this case, m is guaranteed to be an integer only if x is a multiple of 21.

As can be seen from the above equation, the larger the x, the larger the m.

Obviously, when x takes -21, 4*(-21) 21=m-1, i.e., m=-3 is the best result.

by 2 (3x 2+4x+7)=1 4

What you say about this question"The value of 3x squared + 4x + 2/7 is 1/4"There is ambiguity, it may be 3x 2 + 4x + 2 7 = 1 4 but do the same)

3x 2+4x=1 can be solved

So 6x 2 + 8x = 2

Thus 1 (6x 2+8x-1)=1 (2-1)=1

The answer on the first floor is correct, here I will say one more thing: get the question, first read the question carefully, review the question, take your time, the so-called sharpening the knife is not a mistake to chop wood, observe carefully, there must be a harvest, not blindly solve the problem.
