x+49/4x=25
x-2x+3x-4x+...+99x-100x=25
解方程:(2x+5)(4x*x-10x+25)=8x(x*x+1)
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
解分式方程:4/5x+x/(5x-25)=5/(x^2-5x)
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+49/4x=25怎么解
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
25%x+1/4x=13.2
4x+32=25x+0.5
32+4x=25x+0.5
1/2x+1=1/2-1/3x x-2x+3x-4x+...+99x-100x=25
x*x+2x+x*x+10x+x*x+25+2x+x*x+1+1+16+x*x+4x*x+9-12x+16x*x+4-1
