约分:x²-y²/(x-y)²写步骤约分:x²-y²/(x-y)²写步骤约分:x²-y²/(x-y)²写步骤x
约分:x²-y²/(x-y)²写步骤
约分:x²-y²/(x-y)²写步骤
约分:x²-y²/(x-y)²写步骤
x²-y²/(x-y)²=(x+y)(x-y)/(x-y)²=(x+y)/(x-y)
(x+y)(x-y)/(x-y)^2
(x+y)/(x-y)
不过前提是x不等于y
约分(X+Y)Y/XY²
约分:x²-y²/(x-y)²写步骤
约分,急① X³-2X²Y/X²-2XY²②a²-(b-c)²/(a+b)²-c²
约分(初二数学的分式)x²+y²-9-2xy/x²-y²+6x+9
约分:(x²-4)/(xy+2y)
关于分式约分题,1.x²-y²/x²+2xy+y²2.x²+4x+3/ x²+x-63.m²+3m/9-m²
数学分式通分与约分约分 (x²+xy)/(x+y)² x²-y²/(x²-y²)通分2xy/(x+y)²与x/x²-y² x-y/2x+2y与xy/(x+y)²
分式的约分与通分问题约分 (x²+xy)/(x+y)² x²-y²/(x²-y²)通分2xy/(x+y)²与x/x²-y² x-y/2x+2y与xy/(x+y)²
几道数学的约分题.(1)约分.2X²-2/X²-2X+1 3A²-12A+12/4-A² 2 若X²+Y²-2X-6Y+10=0 求分式 2XY-Y²-X²/Y²-X²
用分式表示2x²y(x-y)÷[12xy²(y-x)]的商,并约分
约分:x²+xy/(x+y)²请解析一下为什么是x/(x+y)
约分:(2ax²y)/(3axy²)
约分 1.12(b-a)²/27(a-b)³ 2.3a²b(m-1)/9ab²(1-m) 3.3ab+3b²/a²b+2ab²+b³4.x+2y/x²-4y²5.3a²-ab²/9a²-6ab+b²
分式约分1.a的四次方-1/a²+2a+12.(x+y)² -10(x+y)+25/(x+y)²+25
x²-y²-x-y因式分解
12a的三次方*(y-x)²/27*(x-y) 约分
数学分式约分约分这个分式:x³y-xy³/x³-2x²y+y²x(有步骤)还有一个:x³-16x/x²-8x+16(有步骤)
约分:(1)x²-y²/ax-by+ay-bx(2)x²-y²-9-2xy/x²-y²+6x+9通分:(1)b/2a ,c²/3b ,1/4abc(2)2x/x²-9 ,x+2/x²+5x+6已知1/x - 1/y=2,求3x+xy-3y/y-xy-x的值求求大家了,这是我今天的作业!约分:(1)
