=1/3(9y-3)-2y+2
=3y-1-2y+2
=y+1
=7/9除以7/15-1/3*16
=5-16/3
= -1/3
y (3y^2+8y-3)-6y(3y+2y-1)+9y
通分 y+3/y*y-6y+9,1/2y+6,y-1/y*y-9
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值

2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
(y-4)(3y+2)-(3y-7)(2y+1),其中y=4/3
解方程:3y^2-(2y+1)(y-1)=(y-5)(y+1)
解方程3y^2-(2y+1)(y-2)=(y-5)(y-1)
解方程:3y²-(2y+1)(y-2)=(y-5)(y+1)
解分式方程(y+3)/(y^2+y)-1/(1-y)=4/y要过程
Y(Y-1)-(y-2)*(y+3)=2 Y的解是多少?
Y的平方+3Y-1=0 y+3-1/y=0 y-1/y=-3 (y-1/y)^2=9 y^2+1/y^2-2=9 y^2+1/y^2=11 (y^2+1/y^2)=121 y^4+1/y^4+y^2+1/y^2-2=9y^2+1/y^2=11那个-2是怎么来的?
(y-1分之1)+(y的平方+2y-3)分之2=(y的平方-9)分之y-1
已知7/3*根号(9y)-y-2y*1/y=-2,求y的值
