x=1
Ai kb vs mink ko mink k cho
x(x-1)+(1-x)=0\(\Leftrightarrow x^2-x+1-x=0\Leftrightarrow x^2-2x+1=0\Leftrightarrow\left(x-1\right)^2=0\Leftrightarrow x=1\)
Vậy phương trình có 1 nghiệm duy nhất là x=1
\(x\left(x-1\right)+\left(1-x\right)=0\)
\(x\left(x-1\right)-\left(x-1\right)=0\)
\(\Rightarrow\left(x-1\right)\left(x-1\right)=0\)
\(\Rightarrow\left(x-1\right)^2=0\)
\(\Rightarrow x-1=0\)
\(\Rightarrow x=1\)
x(x-1) + (1-x) =0
x(x-1) - (x-1) =0
(x-1)(x-1) = 0
(x-1)^2 =0
x-1 =0
x=1
