# How do you solve x^2 + 4x = 0?

Mar 28, 2016

#### Answer:

The solutions are :
color(blue)( x=0
 color(blue)(x=-4

#### Explanation:

${x}^{2} + 4 x = 0$

$x$ is common to both terms.
$\textcolor{b l u e}{x} \cdot \left(x + 4\right) = 0$

Equating each of the factors to $0$ will provide the solutions.

• color(blue)( x=0
•  x + 4 =0 ,color(blue)(x=-4
