# How do you solve x^2 - 36x = 0 ?

Apr 10, 2018

Factorize: $x = 0$ or $x = 36$

#### Explanation:

Factorize

$x \left(x - 36\right) = 0$

From the null factor law we can deduce that either $x = 0$ or $\left(x - 36\right) = 0$ in which case $x = 36$.

$x = 0 \text{ or } x = 36$

#### Explanation:

$\text{take out a "color(blue)"common factor } x$

$\Rightarrow x \left(x - 36\right) = 0$

$\text{equate each factor to zero and solve for x}$

$\Rightarrow x = 0$

$x - 36 = 0 \Rightarrow x = 36$
