a,\(x\left(x-1\right)=0\)

\(\Rightarrow\left[\begin{array}{nghiempt}x=0\\x-1=0\end{array}\right.\)

\(\Rightarrow\left[\begin{array}{nghiempt}x=0\\x=1\end{array}\right.\)

b,\(3x^2-6x=0\)

\(\Rightarrow3x\left(x-2\right)=0\)

\(\Rightarrow\left[\begin{array}{nghiempt}3x=0\\x-2=0\end{array}\right.\)

\(\Rightarrow\left[\begin{array}{nghiempt}x=0\\x=2\end{array}\right.\)

c,\(x\left(x-6\right)+10\left(x-6\right)=0\)

\(\Rightarrow\left(x+10\right)\left(x-6\right)=0\)

\(\Rightarrow\left[\begin{array}{nghiempt}x-6=0\\x+10=0\end{array}\right.\)

\(\Rightarrow\left[\begin{array}{nghiempt}x=6\\x=-10\end{array}\right.\)

d,\(x^3-x=0\)

\(\Rightarrow x^2\left(x-1\right)=0\)

\(\Rightarrow\left[\begin{array}{nghiempt}x^2=0\\x-1=0\end{array}\right.\)

\(\Rightarrow\left[\begin{array}{nghiempt}x=0\\x=1\end{array}\right.\)
