x-1/4x=1/36x-1/4x=1/36x-1/4x=1/36x-1/4x=1/36(1-1/4)x=1/363/4x=1/36x=1/36÷3/4x=1/273/4x=1/36x=1/36÷3/
x-1/4x=1/36
x-1/4x=1/36
x-1/4x=1/36
x-1/4x=1/36
(1-1/4)x=1/36
3/4x=1/36
x=1/36÷3/4
x=1/27
3/4x=1/36
x=1/36÷3/4
x=1/27
楼上两位的解法都是正确的,因为楼主你给的这个题有为题,就是在x-1/4x这里,让人产生歧义
1,x-(1/4)x
2,x-1/(4x)
3,(x-1)/4x
你标下注明下,就会有答案了。。
一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X
解方程 式子 6-2x+3x=3x-4x+3x+18 6-x+3x=2x-5x+1 2x-1=5x-36-2x+3x=3x-4x+3x+18 6-x+3x=2x-5x+12x-1=5x-3

(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
(x/x-2)+(2/x*2+2x)-(x+6/x*2-4)化简,=x^2/x(x-2)+(2x-4)/x(x^2-4)-(x^2+6x)/x(x^2-4)=x^2/x(x-2)-(x+2)/x(x-2)=(x-2)(x+1)/x(x-2)=(x+1)/x
提取公因式:已知x*x-5x+1=0 求x*x*x-4x*x-4x-1
X+X+X+(X-1)+(X-2)+(X-3)+(X-4)=10(X-3)+(X-4)
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
x^4+x^3+x^2+x+1=0,x^2006+x^2005+x^2004+x^2003+x^2002
x*x*(1/4)=20x
写过程x(x-1)+2x(x+1)-3x(2x-5)-x(3x-2)+2x(2-x)=-5x(x-2)-4
1.用公式计算:COSX=1-X*X/2!X*X*X*X/4!-X*X*X*X*X*X/6!.直到最后一项的绝对
x-1/4x=1/36
x-4/1=36 x=?
X(X-1)=X
x-1/7x*4=36,
