计算(x²y/-4x)²·(-2x/ay)²÷(-y/2ax²)².
因式分解4x²+4xy-2ax+2bx+y²-ay+by-ab
已知曲线C:x²+y²-4ax+2ay-20+20a=0
化简(a-b)²÷(ax+by-ay-xy)-(a-b)÷(x-y)
设集合A={(X,Y) / ay²-x-1=0},B={(x,y) / 4x²+2x-2y+5=0}
[(3x+y)²-(3x-y)²]÷(4x-2y)计算 怎么做?
计算(x²/x+2y)-x+2y-2
计算4(x+y)^5(x-y)^4÷[2(x+y)³*(y-x)²]
两圆x²+y²+2ax+2ay+2a²-1=0与x²+y²+2bx+2
计算 [12(x+y)³(y-x)]³÷[4(x+y)²(x-y)]²
已知圆x²+y²-4ax+2ay-20+20a=0与x轴相切,求a的值
若圆x²+y²-2ax+ay+2=0的圆心在直线ax-2y-2=0上,则实数a等于多少
设x/z=ln*z/y ,求求az/ax,az/ay,a²z/axay
