Tim x thuoc N biet
( x - 2 )^2016 + \(\left|x-3\right|\) =1
Bai 1 :cho A(x)=2x^2-8x
tim nghiem A(x)
b,tim B(x) biet B(x)=A(x)-3x+2x^2
c,tim ngiem B(x)
Bai2
Cho ham so y=f(x)=x+1
cac diem sau diem nao thuoc do thi ham so :A(0;1).B(1/2;-1). C(-1/2;0)
Tim x thuoc Q
a, (x+1)(x-2)<0
b, (x-2)(x+2/3)>0
tim so huu ti x,y biet: (3x-30) mu 2016+/y-3/ be hon hoac bang 0
Tim x biet
x-4/3=x+2/-2
2x-1/x-3=2x+3/x-1
a)Tim so nguyen x va y biet :
5/x+y/4=1/8
b)Tim so nguyen x de A co gia tri la 1 so nguyen biet :
A=(căn x +1) /(căn x -3) (x lớn hơn hoặc bằng 0)
Tim x thuoc z de ps sau co gia tri la so nguyen
D = 2x - 3 / x - 1
tim x biet |2x+3|-2|4-x|=5
1) tim x thuoc Q
A)|x|=2,1
B)|x|=1 va2/5
C)|x|=17/9 va x<0
D)|x|=0,35 va x>0
2)tim x
A) |x-1,7=2,3
B)|x+3/4|-1/3=0
cac bn giup mih nha
