Question

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

Answer 1

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

Explanation:

`x^2 + 4x = 0`

`x` is common to both terms.
`color(blue)(x ) * ( x +4 ) = 0`

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

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