化简ax^2-3ax=0

化简ax^2-3ax=0 2(ax+by-ax)-(ax+by)^2-(by-ax)^2 其中a=-3 b=0.52(ax+by)(by-ax)-(ax+by)^2-(by-ax)^2 x^4+ax^3+ax^2+ax+1=0 有实数解 求a的取值范围 当|a+2|+(x-3)^2=0时,求1/3(-3ax^2-ax+3)-(-ax^2-1/2ax-1)的值. 解个含参不等式ax^2-ax+2>=0 (ax^2-2ax-3a)÷(x-3)= ax^2-3ax-4a>0 怎么解 ax^3+ax^2+x大于等于0怎么解, y=x^3-2ax^2+2ax求导 分解因式ax²+2ax-3a= y=ax²-2ax-3a（a 1/3(-3ax^2-ax+3)-(-ax^2-1/2ax-1),其中a=-2,x=3 2(ax+by)*(by-ax)-(ax+by)²-(by-ax)²,其中a=-3,x=2分之1 因式分解ax^3+3ax^2+2ax 分解因式：ax^3-ax^2+ax-a 抛物线y=ax^2-3ax+b经过点(-1,0)(3.2), ax^2-2ax+2a-3 ax^2+3ax+a-2
