If the n-th power of the square B of 2010a and the m-th power of - 2009a + 2 B are similar, then M-N=_________

If the n-th power of the square B of 2010a and the m-th power of - 2009a + 2 B are similar, then M-N=_________

∵ the n-th power of the square B of 2010a and the m-th power of - 2009a + the 3-th power of B are similar
∴m+2=2 n-1=3
m=0 n=4
∴m-n=0-4=-4

Solving equation [3x + 18-101 = X-101]
Wrong, it's 3x + 18-101 = x + 101

Transference
2x= 101+101-18
2x=202-18
=184
x=92

3x+18-101=x+101

Transference
3x - x = 101 + 101 - 18
2x = 202 - 18
x = 101 - 9 = 92

20% x + 16 = 18 (3x + 5) + 24 = 47 to solve the equation
20% x + 16 = 18 (3x + 5) + 24 = 47

20%x+16=18
20%x=18-16
20%x=2
x=10
（3x+5)+24=47
3x+29=47
3x=18
x=6

The polynomial x ^ 2 + MX + 12 can be decomposed into the product of two first-order factors. The value of positive integer m is

The values of positive integer m are 13,8,7

If the polynomial x ^ 2 + MX + 18 can be decomposed into the product of two first-order factors, the value of integer m can be obtained

(x+18)(x+1)=x^2+19x+18
(x-18)(x-1)=x^2-19x+18
(x+ 2)(x+9)=x^2+11x+18
(x- 2)(x-9)=x^2-11x+18
(x+ 3)(x+6)=x^2+ 9x+18
(x- 3)(x-6)=x^2- 9x+18

The factorization result of polynomial-3x2n-9xn is ()
A. 3（-x2n+3xn）B. -3（x2n-3xn）C. -3xn（xn+3）D. -3xn（x2+3）

-3x2n-9xn = - 3XN (xn + 3)

What are the coefficients and times of the cubic power a of the monomial 2 * 10 of a

Its coefficient is 2 * 10 ^ 3
Frequency: 1 time

If a polynomial is divided by 2x2y and its quotient is (4x3y2-6x3y + 2x4y2), then the polynomial is ()
A. 2xy-3x+x2yB. 8x6y2-12x6y+4x8y2C. 2x-3xy+x2yD. 8x5y3-12x5y2+4x6y3

According to the meaning: 2x2y · (4x3y2-6x3y + 2x4y2) = 8x5y3-12x5y2 + 4x6y3

If the cube of the polynomial - 5x of X is the square of - 2mx,
If the cube of the polynomial of x-5x-2mx + 2x-1 + x-3nx + 5 does not contain quadratic term and primary term, find the value of M and N, and find the value of the polynomial when x = 2

-The cube of 5x - the square of 2mx + 2x-1 + the square of X - 3nx + 5
＝-5x³-2mx²+2x-1+x²-3nx+5
=-5x³+(1-2m)x²+(2-3n)x+6
It does not contain quadratic term and primary term
1-2m=0
2-3n=0
So: M = 1 / 2, n = 2 / 3
In this case, the polynomial is - 5x & # 179; + 6
When x = 2, the original formula = - 5 × 2 & # 179; + 6 = - 34
