tim x biet \(x-2\sqrt{x}=0\)
tim x biet \((x^2-20)\times\left(x^2-15\right)\left(x^2-10\right)\left(x^2-5\right)< 0\)
Tim x biet
x-4/3=x+2/-2
tim x biet: ||x-1/2|.|2x-3/4||=2x-3/4
|(x+1/2).|2x-3/4||=2x-3/4 tim x biet
tim x, y biet : x.y = -3
Tim x biet
x/1/2= -3/4/5/8

Thanks truoc
tim x biet \(x=\sqrt{x}\)
