# How do you solve x^2-9x=0?

Mar 25, 2016

#### Answer:

$x = 0 \mathmr{and} 9$

#### Explanation:

In order to solve ${x}^{2} - 9 x = 0$
begin by factoring out an $x$.

$x \left(x - 9\right) = 0$
now set each term equal to zero and solve for $x$

$x = 0$

$x - 9 = 0$a
$x \cancel{- 9} \cancel{+ 9} = 0 + 9$
$x = 9$

$x = 0 \mathmr{and} 9$
