计算.(1)2x-1/3=1+(x-3)/2 (2)x-(1-x)/3=(x+2)/6-1
计算:(x+1)(x-2)(x-3)(x-6)
计算 x(x+3)-(x-1)(x-2)
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
计算x^2-5x+6/x^2-1/x^2+x/x-3
如何计算 (x+1)(x+2)(x+3)(x+4)
计算(X-1)(X-2)(X-3)(X-4)
F(X)=2X^3+6X^2-8X计算:(1)F(X)•(-2X);(2)2F(X)-4X
计算:(x+1)x=7 (x-1)(x+2)=30 (3-x)(3-x)+x=9
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
x*(x+1)*(x+2)*(x+3)=360 x=?计算过程以及结果
