计算:3x³[(-1/9X²)]=?
(x³-1)÷(x-1)=?(9x³-6x²-5x+2)÷(3x-1)=?计算
4x²-1/3x²-x·9x³-x/2x^4-x³计算 急
【计算】3x²×+(-x)³
计算(1).(5x-2)(x-3)-(3x-1)(x-4)= (2).(x+3)(x²+9)(x-3)=
计算 (5x-2)(x-3)-(3x-1)(x-4)= (x+3)(x²+9)(x-3)=
计算:3/(x+1)²-3x/(x-1)²=?
计算(-x³+2x²-5)(2x²-3x+1)
计算2x/(x³-1)÷1/(x²+x+1)=
计算5x(2x² -3x+1)
计算(x³-x+1)/(x²-1)-(x²+x)/(x-1)+(2x+3)/(x+1)
计算:若x²+3x-1=0求x³+5x²+5x+8的值
x³-x²/x²+x÷(x²-1) 计算
