The coefficients of polynomials
On the answer and algorithm of Exercise 1.1 in Chapter one of volume two of junior high school (Beijing Normal University Edition), O (∩)_ Thank you. There are rewards (⊙ o ⊙) oh

1. 7h is a monomial; the second, third and fourth are polynomials
2. (1) the polynomial has three terms, the coefficients are - 1, 3 - 1, 2, and the degree of pie is 1, 3, 0
(2) Polynomials have three terms, the coefficients are 1, - 2 and 3, and the degree is 3, 4 and 2

How to calculate the multiplication of three polynomials, such as: (χ - 3) (χ - 3) - 6 (χ & # 178; + χ - 1)

（χ-3）（χ-3）-6（χ²+χ-1）
=x^2-6x+9-6x^2-6x+6
=-5x^2-12x+15

If the inequality system {1m} has a solution, the value range of M is obtained

System of inequalities
There is a solution to the problem
The value range of M is: M

If the solution set of the inequality system {- x + 2m} is x > 4, what is the value range of M?

The answer is: mm; the solution set of x > 4} is x > 4, which is the intersection of the two
It can be seen from the number axis that M is at most equal to 4, and of course it can also be less than 4

Solve the system of inequalities (x-m-1) (x-2m + 1) > 0
X & # 178; - (A & # 178; + a) x + a cubic ＜ 0

(x－m－1)(x－2m＋1)>0
The two roots of equation (x-m-1) (x-2m + 1) = 0 are X1 = m + 1, X2 = 2m-1
(1) If M = 2, then: X1 = X2, then the solution set of inequality is: {x | x ≠ 2};
(2) If MX2, then the solution set is: {x | x > m + 1 or X2, then: x12m-1 or X

If the solution set of inequality (2m-3) x ＞ 1 is 1 / 2 of X ＜ (2m-3), find the value range of M

From 1 / 2 of X ＜ (2m-3), 2m-3 ≠ 0 (otherwise meaningless) and m ＜ 3 / 2 and 2m-3 ＜ 0 are obtained

If x ≥ m, X ≤ n, then the solution set of inequality system X ≥ 3-m, less than or equal to 3-N is?
Hurry!

When m = n, the solution set is {3-m}
When m ≠ n, the solution set is empty

If the system of inequalities x ＜ 8x ＞ m has no solution, then the value range of M is ()
A. m＞8B. m≥8C. m＜8D. m≤8

Because the system of inequalities has no solution, that is, x < 8 and x > m have no common solution set, and m ≥ 8 can be known from the number axis

If the system of inequalities XM has no solution, then the range of M is ()
Such as the title

Because x ＜ 8, X ＞ m has no solution
So m ≥ 8
