(3y+2)(y-4)-3(y-2)(y-3)计算
(3y+2)(y-4)-3(y-2)(y-3)计算
(3y+2)(y-4)-3(y-2)(y-3)计算
解
(3y+2)(y-4)-3(y-2)(y-3)
=3y²-12y+2y-8-3(y²-5y+6)
=3y²-10y-8-3y²+15y-18
=5y-26
﹙3y+2﹚﹙y-4﹚-3﹙y-2﹚﹙y-3﹚
=3y²-10y-8-3y²+15y-18
=5y-26
(3y+2)(y-4)-3(y-2)(y-3)
(y^2)^4y-(-2y)^3y^6=
数学题=y(y+3)-4(y+3)2=(y+3)(y-4y-12)
y (3y^2+8y-3)-6y(3y+2y-1)+9y
6y-(y+2分之y+2-y分之y)÷(y^3-4y-2y^2+8分之y) 怎么算
4y²-4y/y²-2y+1÷(y+1/y-1-y-1/y+1)÷(3y+3)
(y-4)(3y+2)-(3y-7)(2y+1),其中y=4/3
2y+5/3y-6-y/2=5y-4/2y-4
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
解分式方程(y+3)/(y^2+y)-1/(1-y)=4/y要过程
[(-3-y)-y]^2怎麼算,
通分 y+3/y*y-6y+9,1/2y+6,y-1/y*y-9
解(y-3分之2y+y+3分之y)×y分之y²-9
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
