6y^2 11y 4

(y^2)^4y-(-2y)^3y^6=(y^2)^4y-(-2y)^3y^6=y^8*y+8y^3y^6=y^9+8y^9=9y^9

计算：[(y+1)/(y^2-4y+3)减去(y-2)/(y^2-6y+9)]除以(y-5)/(y-1)[(y+1)/(y^2-4y+3)减去(y-2)/(y^2-6y+9)]除以(y-5)/(y-1)=[(y+1)/(y-1)(y-3)减

6y-(y+2分之y+2-y分之y)÷(y^3-4y-2y^2+8分之y)怎么算=6y-[y/(y+2)-y/(y-2)]÷y/[(y³-2y²)-(4y-8)]=6y-y(y-2-y-2)/(y+2)(y-2)×(y-

2y+5/3y-6-y/2=5y-4/2y-42y+5/3y-6-y/2=5y-4/2y-42y+5/3y-1/2y=3y+211/3y-1/2y=3y+22/3y-1/2y=21/6y=2y=12

各位聪明的孩纸们,我只求两道小小的方程.20-y=6y-4(y-11)2-(4-y)=6y-2(y-1)咳咳，那啥，20-y=6y-4(y-11)然后2-(4-y)=6y-2(y-1)又是一道题……我错了……20-y=6y-4(y-11)原

zy-6=y+29y-10=y+5(11x+7)-4=x+30.5zy-6=y+29y-10=y+5(11x+7)-4=x+30.5你能不能把题拍下来给我

zy-6=y+29y-10=y+5(11x+7)-4=x+30.5zy-6=y+29y-10=y+5(11x+7)-4=x+30.5zy十5＝㐅-y=21zy十5＝㐅-y=21

5(y-2)-7(y+3)=11(y+4)5(y-2)-7(y+3)=11(y+4)5y-10-7y-21=11y+44-2y-31=11y+4413y=-75y=-75/135(y-2)-7(y+3)=11(y+4)5y-10-7y-21

y^2-6y-2÷2y-4=(y^2-6y-2)/(2y-4)=(y-2)^2-10还好吧

(4-y)^2-4(1-y)(3+6y)BanAn049是因式分解吧?(4-y)²-4(1-y)(3+6y)=y²-8y+16-4(3+3y-6y²)=y²-8y+16-12-12y+24y²

2-（4-y)=6y-2（y+1)2-（4-y)=6y-2（y+1)2-4+y=6y-2y-26y-2y-y=2-4+23y=0y=0÷3y=0

2-(4-y)=6y-2(y+1)y=0要动脑筋哦~2-(4-y)=6y-2(y+1)2-4+y=6y-2y-2y-6y+2y=-2-2+4-3y=0y=0化简2-4y=6y-2y-2y-2=4y-2y=4yy=0

y^-6y-2;2y-4=多少?(y-2)^2-10

y(5y-2)=6-4y解方程5y平方-2y=6-4y-2y+4y=6-5y平方5y－2y=6-4y5y+2y=6此为二次方程你确定你学了-2

解方程4y-2=y-6+7y4y-2=y-6+7y-2+6=y+7y-4y4=4y4y=4y=4/4y=114y-y-7y=-6+2-4y=-4y=1移项4y-y-7y=-6+2-4y=-4y=14y-y-7y=-6+2-4y=-4y=14

2y+3等于11-6y8y=8y=1Y=1y=1

6Y^2-11Y-10因式分解十字相乘法6y^2-11y-10=(2y-5)(3y+2)(3y+2)(2y-5)

分解:6y^2+11y-106y^2+11y-10=（2y+5)(3y-2)

因式分解：6y^2-11y-106y^2-11y-10=(2y-5)(3y+2)

6y^2-11y-10=(?)(?)6y^2-11y-10=(2y-5)(3y+2)
