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
计算:[(y+1)/(y^2-4y+3)减去(y-2)/(y^2-6y+9)]除以(y-5)/(y-1)
y (3y^2+8y-3)-6y(3y+2y-1)+9y
解3y+5/3y-6=1/2+5y-4/2y-4
计算(3y-1)(2y+3)-(6y-5)(y-4)
(3y-1)(2y-3)+(6y-5)(y-4)=?xie
(3y-1)(2y一3)十(6y一5)(y一4)
(3y-1)(2y-3)+(6y+5)(y-4)=?
解方程3/y-1+5y-2/y2-y=6/y
5y∧2-(y-2)(3y+1)-2(y+1)(y-5)
解方程:3y^2-(2y+1)(y-1)=(y-5)(y+1)
2(y-4)(3y+2)-5(-3y+7)(y+1),其中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)
解不等式组2y+3小于9-y,6y-1<5,3y+7≥2-y
