2a(x+1)^2-2ax2a(x+1)^2-2ax2a(x+1)^2-2ax解由2a(x+1)^2-2ax=2a(x^2+2x+1)-2ax=2ax^2+4ax+2a-2ax=2ax^2+2ax+2
2a(x+1)^2-2ax
2a(x+1)^2-2ax
2a(x+1)^2-2ax
解由2a(x+1)^2-2ax
=2a(x^2+2x+1)-2ax
=2ax^2+4ax+2a-2ax
=2ax^2+2ax+2a
发的广告的说过话
x^2-ax-a-1
关于x不等式ax^2+ax+a
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
ax^2-a^2x-x+a怎样因式分解为（x-a）(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
求该函数(x^2 - x - 1/a)e^ax (a>导数e^ax * (ax+2)(x-1)
