Enumerate the five times the four practical, what does the four time four practic mean

Four quadruples:PolynomialsThe highest order is four, and there are four terms in the polynomialMonomial

In polynomials, each monomial is called an term of the polynomial; The highest number of times of each term is called the number of times of the polynomial. A polynomial is a few terms, which is called a few terms.

For example, if x 4+x 2-44 is a quadruple trinomial, the highest degree of this polynomial is 4 times and consists of 3 mononomial components.

When calculating, it should be noted that the same number of times are the same except for the coefficients, and the formulas of Hu Shu are added, and the coefficients are added together, and the number of times is unchanged.

The polynomial is composed of at least two monomials.

"quadruple trinomial" is generally not written as "quadruple trinomial".

It means that in the polynomial, the highest power of x is 5th, that is, the 5th power of x, and the polynomial has a total of 4 terms, which is the meaning of "5th quadracial about x".

Five-time quadrally:

Then the number of times (m+2)x ny is five.

then n+1=5 and m+2≠0.

n=4 and m≠-2.

Addition vs. multiplication.

The sum of finite monomials is called a polynomial. A polynomial expressed by the sum of the monomials of different classes, where the highest number of monomials with coefficients not zero is called the degree of this polynomial.

The addition of a polynomial means that the coefficients of the same terms in the polynomial are added and the letters remain the same (i.e., the town sells and merges the same terms). Multiplication of polynomials refers to the multiplication of each monomial in one polynomial by multiplying each monomial in another polynomial and merging similar terms.

f: x1, x2 ,..., the set of the whole polynomial of xn fx, for the addition and multiplication of the polynomial become a ring, which is a whole ring with unit elements.

It means that in the polynomial, the highest power of x is 5th, that is, the 5th power of x, and the polynomial has a total of 4 terms, which is the meaning of "5th quadracial about x".

Five-time quadrally:

Then the number of times (m+2)x ny is five.

then n+1=5 and m+2≠0.

n=4 and m≠-2.

x + m+2) x n y - xy + 3 (Note: to the power of the power).

1. Five-time quadrive.

Then the number of (m+2)x n y is five times, then n+1 = 5 and m+2 ≠ 0

n=4 and m≠-2.

2. Quadruple trinomial.

Then (m+2)x n y is zero.

m+2 = 0 ，m = - 2

n Unlimited. or m+2)x n y - xy ] is zero n=1m+2 -1 = 0 , m = - 1

It means that in the polynomial, the number of terms with the highest degree is five times, and there are four terms in this polynomial, and such a polynomial is called a five-order quadrive. An algebraic formula consisting of the sum of several monomials is called a polynomial (in subtraction, subtracting a number equals adding its opposite). Each monomial in a polynomial is called a polynomial term, and the highest degree of these monomials is the number of times the polynomial is like a thing.

Represents a number or letter monomial:

1. The product of any letter and number (in the division, there is: dividing by a number is equal to multiplying the reciprocal of this number).

2. A letter or number is also called a monomial.

3. The formula that does not contain the product of unknowns in the denominator is called a monomial.

1. The number of monomials: In a monomial, the sum of the exponents of all letters is called the number of times of this monomial.

2. Coefficients of monomials: the numerical factors in monomials. For example, the coefficient of 2xy is 2; The coefficient of -5zy is -5.

3. The exponent of the letter t is 1,100t is a monomial; In the monomial vt, the sum of the exponents of the letters v and t is 2, and vt is a quadratic monomial.
