x+16=1/5x+25,
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
x/x-4 - 32/x的平方+16=1 x+1/x + 5X/x+1=6
解方程:(2x+5)(4x*x-10x+25)=8x(x*x+1)
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
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
X+(3X-16)÷25%=10(x+1)
提取公因式:已知x*x-5x+1=0 求x*x*x-4x*x-4x-1
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
