On the quadratic polynomial of X
A quadratic polynomial about X, when x = 1, the value of the polynomial is - 1, what is the sum of the coefficients (including the constant term) of the polynomial? Why

Let this polynomial ax ^ 2 + BX + C. from the meaning of the problem, we know that when x = 1, the value of the polynomial is - 1, and substitute it into a + B + C = - 1 (that is, the sum of the coefficients (including the constant term) of the polynomial)

Finding the system of inequalities 2x-3

2x-3＜9-x;
3x＜12;
x＜4;
-3x/2≤x-5/2;
-3x≤2x-5;
-5x≤-5;
x≥1;
∴1≤x＜4;
The integer solution is 1,2,3
If you don't understand this question, you can ask,

Is 2 + x a polynomial

No
It's a fraction

Known inequality system x-a > 0, x-a

Equation group x-a > 0, x-a

In the polynomials x + 1, x + 2, as follows
In polynomial x + 1, x + 2, x + 3, x ^ 2 + 2x-3, x ^ 2 + 2x-1, x ^ + 2x + 3, which are the factors of polynomial (x ^ 2 + 2x) ^ 4-10 (x ^ 2 + 2x) ^ 2 + 9?

（x+1) (x^2+2x－1) (x+3) x^+2x+3

If x-a > 0, x-a

x-a>0 x-a

Is (x + y) / 2 a polynomial

Yes. Monomial: 1. An algebraic formula in the form of the product of any letter and number (in division, dividing by a number is equal to multiplying the reciprocal of the number). 2. A letter or number is also called a monomial. 3. There is no letter in the denominator (the monomial is an integral, not a fraction). A, - 5,1x, 2XY, X / 2 are all monomials, and 0

(log2^3 +log3^5) x ( log3^5 +log9^5 ) x lg 2 ,
I'm very poor, so I'd better explain,
(log2^3 +log5^3) x ( log3^5 +log9^5 ) x lg 2

The logarithm doesn't even have a bottom!

What are the sum of the following polynomials? How many times and terms are they?
(1) The square of 3x, the square of Y - the square of 5xy + the fifth power of X - 6
(2) The square of - S - the square of 2S + the square of 6T
(3) Cube of 2 / 3x by

(1) The square of 3x, the square of Y - the square of 5xy + the fifth power of X - 6 is the sum of the four terms of "the square of 3x, the square of Y, - the square of 5xy, + the fifth power of X, - 6". It is the square of quintic quaternion (2) - s, the square of - 2S, the square of + 6T ". It is the sum of the three terms of" - the square of S, - the square of 2S, the square of + 6T "
