Factorization (x + y + Z) ^ 3 - (y + z-x) ^ 3 - (Z + X-Y) ^ 3 - (x + Y-Z) ^ 3
kkkkkkkkk
(x+y+z)^3-(y+z-x)^3-(z+x-y)^3-(x+y-z)^3=((x+y+z)^3-(y+z-x)^3)-((z+x-y)^3+(x+y-z)^3)=(x+y+z-y-z+x)((x+y+z)^2+(x+y+z)(y+z-x)+(y+z-x)^2)-(z+x-y+x-z+y)((z+x-y)^2-(z+x-y)(x+y-z)+(x+y-z)^2)=2x((x+y+z)^2+(x+...
Write a linear equation of one variable satisfying the following conditions at the same time: ① the coefficient of an unknown number is 2; ② the solution of the equation is 3, then such an equation can be written as:______ .
This equation can be written as: 2x-6 = 0. (the answer is not unique). So the answer is: 2x-6 = 0
If a + 2B = 0, find the value of fraction a ^ 2 + 2ab-b ^ 2 / 2A ^ 2 + ab-b ^ 2
a+2b=0
a=-2b
(a²+2ab-b²)/(2a²+ab-b²)
=(4b²-4b²-b²)/(8b²-2b²-b²)
=-b²/(5b²)
=-1/5
Factorization of (X-Y) ^ 3-2 (Y-X) ^ 2
(x-y)^3-2(y-x)^2
=(x-y)^3-2(x-y)^2
=(x-y)^2(x-y-2)
(x-y)^3-2(y-x)^2=(x-y)^3-2(x-y)^2
=(x-y)^2(x-y-2)
Write out a linear equation of one variable satisfying the following conditions: ① the coefficient of an unknown number is 1 / 2, ② the solution of the equation is 3, such an equation can

Given that a of B = 2 of 3, find the square of a + 2 of 2 B and the square of 2A - AB + B
A / b = 2 / 3, (2a & # 178; - AB + B & # 178;) / (A & # 178; + 2B & # 178;) a & # 178; / B & # 178; = 4 / 9, so a & # 178; = (4 / 9) B & # 178;, and then replace all a & # 178; with B & # 178;, and the final answer is 1 / 2
a/b=2/3
(2a²-ab+b²)/(a²+2b²)=(2a²/b²-a/b+1)/(a²/b²+2)=(2×4/9-2/3+1)/(4/9+2)=(11/9)/(22/9)=1/2
Factorization of (X-Y) ^ 2 - (X-Y) ^ 3
2、(x+y)^2-(x+y)^3
3、(x-y)^2-(y-x)^3
(x-y)^2-(x-y)^3=(x-y)^2[1-(x-y)]=(x-y)^2(1-x+y)2.(x+y)^2-(x+y)^3=(x+y)^2[1-(x+y)]=(x+y)^2(1-x-y)3、(x-y)^2-(y-x)^3=(x-y)^2+(x-y)^3=(x-y)^2[1+(x+y)]=(x-y)^2(1+x+y)
Write out a linear equation with one variable satisfying the following conditions: 1. The coefficient of an unknown number is 2, 2. The solution of the equation is 3
Answer: 2x + 1 = 7
I wish learning every day, do not understand can continue to ask me
Coefficient refers to the number in front of X. 0 = 2x-6 should be regarded as one. When x = 3, the equal sign holds
Given A-B = 2 ab = - 3, find (2a + 3b-2ab) - (a + 4B + AB) - (3AB + 2b-2a)
(2a+3b-2ab)-(a+4b+ab)-(3ab+2b-2a)
=2a+3b-2ab-a-4b-ab-3ab-2b+2a
=(2a-a+2a)+(3b-4b-2b)+(-2ab-ab-3ab)
=3a-3b-6ab
=3(a-b)-6ab
=3*2-6*(-3)
=24
The above answer is correct
Twenty-four
