(x+5)/(x-1)≥2
(x+5)/(x-1)≥2
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
(1)x²-2x+1/x²+9x-10≥0 (2)3x²-7x/2x²-5x-3
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
化简 x(x-1)+2x(x+1)-3x(2x-5)
x(x平方-1)+2X平方(X+1)-3X(2X-5)帮个忙
用公式法解下列方程x²-4x+1=0-5x²-3x+2=02(x²-2)+2x=x(3x-
(x-1)/x -(1-x)/(x+1)=(5x-5)/(2x+2) x等于多少
已知函数f(x)={-x^2+(1/2)x,x
x-3(x-2)≥14 (3x-1)/3>x-5/2
