How do you solve x^2-2x=0 ?

Feb 18, 2016

$x = 0 , x = 2$

Explanation:

${x}^{2} - 2 x = 0$

$x$ is common to both terms of the L.H.S:

$\textcolor{b l u e}{x} \textcolor{g r e e n}{\left(x - 2\right)} = 0$

Equating both factors to zero to obtain the values of $x$:
1) $\textcolor{b l u e}{x} = 0$

2) $\textcolor{g r e e n}{x - 2} = 0 , x = 2$

The values for $x$ are :
$x = 0 , x = 2$
