Calculation of (M + 2n / n-m) - (n / m-n) + (2m / n-m) process

Calculation of (M + 2n / n-m) - (n / m-n) + (2m / n-m) process

（m-n)^3+(n-m)m^2
=（m-n)^3-(m-n)m^2
=(m-n)[(m-n)^2-m^2]
=(m-n)(m-n+m)(m-n-m)
=-n(m-n)(2m-n)
=-n(2m^2-3mn+n^2)
=-2m^2n+3mn^2-n^3

Calculation (2m / m ^ 2-N ^ 2) - (m-2n / N ^ 2-m ^ 2) + (n / N ^ 2-m ^ 2)
M squared minus n squared minus 2m, n squared minus m squared minus 2n plus, n squared minus n squared

(2m/m^2-n^2)-(m-2n/n^2-m^2）+（n/n^2-m^2）=(2m/m²-n²)+(m-2n/m²-n²）-（n/m²-n²）=(2m+m-2n-n)/(m²-n²)=3(m-n)/(m-n)(m+n)=3/(m+n)

The basis of operation (a ^ 2 * a ^ m) ^ n = a ^ 2n * a ^ 2m is
The answer is to take the product and then the power

The power of product is: (a * b) ^ n = (a ^ n) * (b ^ n)
The power of the power is: A ^ m * a ^ m *. * a ^ m (a total of n) = (a ^ m) ^ n (in this problem, (a ^ 2 * a ^ m) is in the example (a ^ m))

Calculation 1. M ^ 2-N ^ 2-2m (M + n)
2.(a+b)^2+2(a^2+ab)+a^2
3.999^3+3*999^2+3*999+1
4.(m-n)^2013-9(m-n)^2014

1、-（m+n）^2
2、（2a+b)^2
3、(999+1)^3=1000^3
4、.(m-n)^2013(1-9m+9n)

What's the coefficient of 2 m squared

The coefficient of 2 / 3 square n is 2 / 3

75m square n - [2 / 3MN square - (2 / 2m square n-1.3mn Square)]

75m square n - [2 / 3MN square - (2 / 3M square n-1.3mn Square)] = 0.75m square n-1.5mn square + 2 / 3M square n-1.3mn square = (3 / 4 + 2 / 3) m square n - (1.5 + 1.3) Mn square = 17 / 12m square n-2.8mn square

Given the square of | 3m-12 | + (2 / N + 3 + 1) = 0, then 2m-n = (2 / N + 3, which is the separated + 1)

I'm glad to answer for you ~ first let two parts equal to 0, namely | 3m-12 | = 0 & nbsp; & nbsp; & nbsp; (n / 2 & nbsp; + & nbsp; 3 + 1) ^ 2 [(half n + 3 plus 1) ^ 2? Or (half n + 3 + 1) ^ 2..] then solve M = 4 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp

Given | 3M − 12 | + 2 (n + 32 + 1) 2 = 0, then the value of 2m-n is______ ．

∵ 3M − 12 | + 2 (n + 32 + 1) 2 = 0; ∵ 3m-12 = 0, N + 32 + 1 = 0; the solution is m = 4, n = - 5; then 2m-n = 2 × 4 - (- 5) = 13

Using factorization to solve the equation x & # 178; - MX = NX (m, n are known numbers)

x[x-(m+n)]=0
X = 0 or M + n

Factorization x ^ 2m + 2-x ^ 2m + 1

Original formula = x ^ (2m + 1) (x-1)
