(ax+2a^2-2a^2+1)/(x+2a)怎么化简成a+(1-2a^2)/(x+2a).(ax+2a^2-2a^2+1)/(x+2a)怎么化简成a+(1-2a^2)/(x+2a).(ax+2a^2
(ax+2a^2-2a^2+1)/(x+2a)怎么化简成a+(1-2a^2)/(x+2a).
(ax+2a^2-2a^2+1)/(x+2a)怎么化简成a+(1-2a^2)/(x+2a).
(ax+2a^2-2a^2+1)/(x+2a)怎么化简成a+(1-2a^2)/(x+2a).
(ax+2a^2-2a^2+1)/(x+2a)
=[a(x+2a)+1-2a²)]/(x+2a)
=a(x+2a)/(x+2a) +(1-2a²)/(x+2a)
=2 + (1-2a²)/(x+2a)

x^2-ax-a-1
关于x不等式ax^2+ax+a
ax^2-a^2x-x+a怎样因式分解为(x-a)(ax-1),
因式分解:x^3-ax^2-2ax+a^2-1
把a+ax+ax^2+x^2-1因式分解
若A={x|ax^2-ax+1
关于x的不等式ax^2+ax+a-1
x^3+ax^2+ax+a-1因式分解谢谢了
若集合A={x丨ax^2-ax+1
2a(x+1)^2-2ax
ax^2-(a+1)x+1
ax^2-(a-1)x+1
ax^2-(a-1)x+1
解不等式ax^2-x+1-a
x²-2ax+a²-1
(a+1)/x+2ax+4
x^2-ax+1-4a
aX-a>X+1-2a 的解是X
