解方乘(1-0.5x)/0.3-( 2x-1)/3=0.3x/0.02
解方乘(1-0.5x)/0.3-( 2x-1)/3=0.3x/0.02
1-0.5x/0.3-2/3x=0.3x/0.2x+1
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
1、0.3X-0.4X=0.5 2、5X-2.5X+3.5X=-18 3、X-2/5X=-3+6
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
x^4+x^3+x^2+x+1=0,x^2006+x^2005+x^2004+x^2003+x^2002
160乘25%-1.3x=17.9 x/5-x/6=0.4 3(x+2)=40+11 0.3/0.5=x+1/2x-1
(3x-1)/0.5=(4-x)/0.3+(3x+5)/1.5 x得多少?
x-1)(X-2)(x-3)...(x-50)+x(x-2)(X-3)...(X-50)+...+x(x-1)(x-2)
(X-4)(x-2)-2(X-1)(X+3)其中X=-0.5
f(x-1)=x^2-2x+3(x
解方程0.3x+0.8/0.5-0.02x+0.3/0.3-1=0.8x-0.4/3
