(12x^3-18x^2+6x)/(-6x)=
已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
2x+3x+4x+5x+x+6x+7x=100
1/x(x+3)+1/(x+3)(x+6)+1/(x+6)(x+9)=3/2x+18
X(x+3)分之一+(X+3)(X+6)分之一+(X+6)(X+9)分之一=2x+18分之三
约分 (X的平方+4x+3)(2x-x)^/(X^+X)(X^+X-6),
(x+2)(x-3)(x-6)(x-1)=0
x-o.8x=6 12x-8x=4.8 3x-8=16 7.5x-2x x-0.7x=3.6 求答案
5x+9x=6x*2+12 x+9-x/3=4
x^3×x^5×x+(x^3)^12+4(x^6)^2=?
