分解因式5a²b(x-y)³-30ab²(y-x)²
若a=3x+5y,b=y-3x,求a^2-2ab+b^2
1.3x-2(2+x) 2.2x-(x+3y)-(-x-y)+(x-y) 3.5a²b-[ 2ab²
因式分解:(1)3a(x-y)-5b(y-x)(2)a3b+2a2b-3ab.
.m(x-y)²-x+y 5(y-x)²+3(x-y) 15*(a-b)²-3y(b-a)
(a-b)(5x-3y)-(b-a)(3x+5y)
3a-5b=-2,2a+7b=9.a=() b= () x+3y=10,x-3y=-2.x=(),y=() 3x-5y+
下列各式正确的是 1.3/X+5/X=15/X^2 2.B/A-A/B=B-A/AB 3.4X/X-Y+4Y/Y-X=4
x²-xy-30y² a²(x-y)³-b(y-x)² a(x-y)²-b(y-x)²分解因式哦
设集合A={(x,y)|3x+2y=5},B={(x,y)|4x-y=3},求A∩B
