=>x^2-2x=0=>x^2=2x=>x=2
Hoặc 3x-7=0=>x=7/3( loại)
Vậy x=2
=>x^2-2x=0=>x^2=2x=>x=2
Hoặc 3x-7=0=>x=7/3( loại)
Vậy x=2
bai 1 so cac gia tri nguyen cua x de gia tri tuyet doi cua x + gia tri tuyet doi cua x-2 =0
bai 2 so cac gia tri nguyen cua x thoa man gia tri tuyet doi cua x-3 + gia tri tuyet doi cua 8-2x = 1 là
so cac gia tri nguyen cua x thoa man (2x+3)(2x+10)<0
cac gia tri nguyen cua x thoa man(2x+3)(2x+10)<0
gia tri nguyen cua x thoa man (2x-3)(x-1/4) < 0
cho x la so nguyen thoa man : -7/25<x/30<-1/5. so gia tri cua x thoa man la
so gia tri cua x thoa man (x^2+1)+/x-1/+/x^3+1/=0
tick nhanh cho mk vs
gia tri cua x thoa man 3(x-2)-2(x+1)= -30
So cac gia tri nguyen cua x thoa man |x.(x^2 - 3)| = x la
So gia tri nguyen cua x thoa man : /x2-5/+/5-x2/=40
/.../ la gia tri tuyet doi.
