Step-by-step explanation:
Assuming we want to solve for x in:
[tex] {x}^{2} + 2x = 0[/tex]
Then we factor to get:
[tex]x(x + 2) = 0[/tex]
Apply the zero product principle to get:
[tex]x = 0 \: or \: x + 2 = 0[/tex]
[tex]x = 0 \: or \: x = - 2[/tex]
The question is not all that clear, so I assume you are solving for x in the completed quadratic equation.
