2/3×(3x-6)-1/2(2x-4)=4
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
6/(x+1)=(x+5)/[x(x+1)] (3-x)/(x-4)+1/(4-x)=1 2/(1+x)-3/(1-x)
1、x*(x+3)*(x+6)*(x+9)=68040 2、x*(x+1)*(x+2)*(x+3)*(x+4)=5544
5x-3(2x+1)=6x-4(5-3x)求x
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
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
