(3x²y-2xy²)/M=-3x+2,M等于多少?(3x²y-2xy²)/M=-3x+2,M等于多少?(3x²y-2xy²)/M=-3x+
(3x²y-2xy²)/M=-3x+2,M等于多少?
(3x²y-2xy²)/M=-3x+2,M等于多少?
(3x²y-2xy²)/M=-3x+2,M等于多少?
-xy.
若x²+xy-2y²=0,则x²+3xy+y²/x²+y²
x²+xy-2y²=0则x²+3xy+y²/x²+y²
计算:4xy²-3x²y-{3x²y-[2xy²-4x²y+2(x²y-2xy²)]急
6x²-xy-15y²=0 求x²-2xy+4y²/2x²-3xy-3y²告诉下
6x²-xy-15y²=0 求2x²-3xy-3y²分之x²-2xy+4y²
已知:x²+xy=3,xy+y²=-2 求:2x²-xy-3y²
x²-2xy+y²-9
因式分解X²-3Xy+2y²+X-2
因式分解 x²-3xy+2y²+x-2
已知x² -XY = 2,Y² -XY= 5,求x² - 4x Y+ Y² = 2x² + xY -3Y² = x² 已知x² -XY = 2,Y² -XY= 5,求x² - 4x Y+ Y² = 2x² + xY -3Y² = x² + xY- 2Y² =求x² - 4x Y+ Y² =
x/y=2,求x²-3xy+y²/2x²-3xy+5y²
已知x/y=3,求x²+2xy-3y²/x²-2xy+y²
已知x/y=3,求x²+2xy-3y²/x²-xy+y²的值
x/y=2,求分式x²-xy+3y²/x²+xy+6y²
1.y²-5xy-6x² 2.m²-3mn+2n²
X²+xy²-x²-y²-3xy+2x+2y-1分解因式
x²+xy-2y²=0,则x²+3xy+y²/x²+y²=?如题目.详细计算过程
数于式的提如果x²+xy-2y²=0,则(x²+3xy+y²)/(x²+y²)等于?
