Factorization of x ^ 3-x-y ^ 2-y

Factorization of x ^ 3-x-y ^ 2-y

x^3+x^2y-xy^2-y^3
=x^2(X+Y)-y^2(x+y)
=(x+y)(x^2-y^2)
=(x+y)(x+y)(x-y)
=(x+y)^2(x-y)
Your result is right, but it can be decomposed again!
(x + y) ^ 2 (X-Y) is complete!
Write 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, fast
1/2x+2=7/2
It is known that m and N are monomials. If 1 / 2A? B + M = 1 / 2Ab (n + 2b), then M = -, n=——
1/2a?b+m=1/2ab(n+2b)
The question mark is square
Change to 1 / 2A & # 178; B + M = 1 / 2Ab (n + 2b)
1/2a²b+m=1/2ab(n+2b)
1/2a²b+m=1/2abn+ab²
m=1/2abn+1/2ab²=1/2ab(n+b)
∵ m and N are monomials
∴n=-b m=0
1/2a²b+m=1/2ab(n+2b)=(1/2)anb+ab²
There are: 1 / 2A & # 178; b = (1 / 2) anb, M = AB & # 178;
The solution is: n = a, M = AB & # 178;
If x = root 17-1, find the value of x cube + 2x square + 3x-1
Process xiexie
X cube + 2x square + 3x-1
=x(x²+2x+1)+2x-1
=x(x+1)²+2x-1
=X (radical 17-1 + 1) ² + 2x-1
=17x+2x-1
=19x-1
=19 (radical 17-1) - 1
=19 roots 17-20
X cube + 2x square + 3x-1
=X cube + 3x square + 3x + 1 - x square - 2
=(x + 1) cubic-xsquare-2
=17√17－17－2
=17√17－19
Write a linear equation with one variable so that its solution is two-thirds negative and the coefficient of the unknown is a positive integer
3x+2=0
Given that 1 / A-1 / b = 4, then the value of 2a-2b + a-2ab-b is equal to
There are four options: a.6 B. - 6 C.D. - 2 / 7
1 / A-1 / b = 4
2a-2b + 2Ab a-2ab-b
=The denominator of (a-2ab-b) / (2a-2b + 2Ab) is divided by ab at the same time
=(1/b-2-1/a)/(2/b-2/a+2)
=-6/(-6)
=1
If you don't have the option, you can check whether the original question is correct
3x²-2x-1=0 x=?
3x²-2x-1=0
3x-2-1/x=0
3/4x=2
x = 8/3
Write out a linear equation of one variable so that its solution is - 1 / 2 and the coefficient of the unknown is a positive integer
-10X/20X=-1/2
-(10/20)X=-1/2
-1/2X=-1/2
X=1
2X+1=2
-10X/20X=-1/2
-(10/20)X=-1/2
-1/2X=-1/2
X=1
X = - 1 / 2 multiply both sides by positive integers at the same time
M power of a = n power of 2A = 8 find m + n power of a
M + n power of a
=M power of a * n power of a
=2*8
