The degree of a polynomial refers to the degree of the item with the highest degree in each item of a polynomial. A is a cubic polynomial about a, so the degree of the item with the highest degree in polynomial A is 3; B is a quadratic polynomial about a, so the degree of the item with the highest degree in polynomial B is 2

In the following inequalities, the absolute solutions of a, 5x-2 greater than or equal to 4x B, X-2 (x-1) > - x C, X-2 (x-1) less than or equal to - x D, X are all real numbers
Check value > 0

A. The solution of 5x-2 ≥ 4x is x ≥ 2
B、x-2(x-1)＞-x
x-2x+2>-x
2>0
So the answer is B, no matter what value x takes

Let a be a quadratic trinomial and B be a cubic pentanomial, then in the result of a * B, the degree of the polynomial must be___ benefit
Use the square difference formula to calculate (1 + 1 / 2) (1 + 1 / 4) (1 + 1 / 16) (1 + 1 / 256) + 1 / 2 ^ 15

Let a be a quadratic trinomial and B be a cubic pentanomial, then in the result of a * B, the degree of the polynomial must be degree 5. (1 + 1 / 2) (1 + 1 / 4) (1 + 1 / 16) (1 + 1 / 256) + 1 / 2 ^ 15 = 2 * (1 - 1 / 2) (1 + 1 / 2) (1 + 1 / 4) (1 + 1 / 16) (1 + 1 / 256) + 1 / 2 ^ 15 = 2 * (1 - 1 / 2 ^ 2) (1 + 1 / 2

It is known that the solution set of inequality 1 / (x-a) > x + A is {f | X

1/(x-a)>x+a
When x > A, 1 > x ^ 2-A ^ 2 is x ^ 2

If a is a cubic polynomial and B is a quadratic polynomial, then A-B must be

If a is a cubic polynomial and B is a quadratic polynomial, then A-B must be a cubic polynomial

Given the inequality | x2-5x + 6 | ≤ x + A, where a is a real number, if the inequality has exactly three integer solutions, find all the values of a satisfying the condition

Let the quadratic function y = | x2-5x + 6 |, let y = 0, the solution is: x = 2 or 3, then the intersection of the function and X axis is a (2, 0) or B (3, 0), when x = 4, y = 2, when x = 0, y = 6, then the function must pass through point C (4, 2) and point d (0, 6)

If a is a cubic polynomial and B is a quadratic polynomial, then A-B must be
The answer is a cubic integral, and it's better to analyze it

First of all, a polynomial of degree three belongs to an integral. A polynomial of degree three is a polynomial of degree three, and a polynomial of degree two is a polynomial of degree two. The highest degree of A-B must be of degree three, that is, it must be an integral of degree three
