∵0<a<1
∴㏒ax在全体定义域内单调递减
根据函数的定义,x1>x2,f(x1)<f(x2),则函数在定义域内为减函数。
∴2x-y+1<3y-x+2 即4y-3x+1=0
且2x-y+1>0
3y-x+2>0
∴利用线性规划
红色虚线:y=-x
红色实线:y=-x+λ
交点(-1,-1)
∴λ=-2请问可以写正常...

(x+y)a-(x-y)a 化简~
多项式a(x-y)+a(x-y)
因式分解(x+y+a)²-(x-y-a)²
因式分解,(a-b)(x-y)-(b-a)(x-y)(a-b)(x-y)-(b-a)(x+y)
如何解因式分解x(x-y)(a-b)-y(y-x)(b-a)
(x+y)³-xy(x+y)=(x+y)*A,则A=?
(2y-x)(y-2x)-a(y+x+a)
(x+y)-(x-a)打开括号后,是不是应该是 X+Y-X+A
2(x-y)+a(x-y)因式分解
8a(x-y)平方-4b(y-x)
通分x/a(x-y),y/b(y-x) 通分 a/(y-x)的平方,b/(x-y)*(x+y)
把下列各式因式分解 (1)、a^2(x-y)-4a(y-x)+4(x-y) (2)、(x+y)(x-y)-(x+z)(x-z)
[1]a(x-2y)-b(2y-x)+d(2x-4y) [2]x平方-2xy+y平方-2x+2y+1 【3】一(a-x)(a-y)-x(y-a)(X-a)[1]a(x-2y)-b(2y-x)+d(2x-4y) [2]x平方-2xy+y平方-2x+2y+1【3】一(a-x)(a-y)-x(y-a)(X-a) 分解因式,急求!
已知x+y+z=3a,(a≠0,x,y,z不全等).求(x-a)(y-a)+(y-a)(z-a)+(z-a)(x-a)/(x-a)^2+(y-a)^2+(z-a)^2
x+y+z=3a(a不等于0,x,y,z不全相等)求[(x-a)(y-a)+(y-a)(z-a)+(z-a)(x-a)]/[(x-a)^2+(y-a)^2+(z-a)^2]
(x+y)²+2(y-x) 因式分解 怎么弄 我这还有几道题(x+y)²-(x+y)(x-z)+(x+y)(y+z)X(X-a)(x-b)-y(a-x)(b-x)x(x+y)(x-y)-x(x+y)²(2a+b)(2a-3b)-3b(2a+b)(a+b)²-9(a-b)²(a²+b²)²-a²b²9(x-y)-y&
(2a+b)(2a-3b)+3a(2a+b)和x(x+y)(x-y)-x(x+y)²4a(x+y)-6x-6y和啊a(a-b)-ab+b²
关于X、Y的方程组{X+Y=A+1,X-Y=3A-3的解X>Y,那么()A:A>1B:A
