(29-x-x^2)/(5x+2)<1
移项(x^2-4x-31)/(5x+2)>0
然后怎么化解
(29-x-x^2)/(5x+2)<1 移项(x^2-4x-31)/(5x+2)>0然后怎么化解
(29-x-x^2)/(5x+2)<1
(x^2+6x-27)(5x+2)>0
(x+9)(x-3)(5x+2)>0
∴x>3或-9

解下列方程!就三道!解下列方程.1、x/x-2 - 1-x²/x²-5x = 2x/x-3(x/x-2 - 1-x²不是一起的!)2、5x/x²+x-6 - 5-2x/x²-x-12=7x-10/x²-6x+8(5x/x²+x-6 - 5-2x不是一起的!)3、x-4/x-5 + x-8/x-9=x-7/x-
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
x+5/x+1-3x-3/x+5=8x+28/x^2+4X-5-2(x+5)/(x+1)-(3x-3)/(x+5)=(8x+28)/(x^2+4X-5)-2
1.(1/X-1 )-2=X^-3X/X^-12.(X/X+1)^+5(X/X+1)+6=03.(8(X^+2X)/X^-1)+ 3(X^-1)/X^+2x
