$x = - 2 or x = 0$ $x = -2 or x=0$

Although there are only 2 terms, the equation is still a quadratic.
Always check to see if it factorises. There is a common factor.

$x (x + 2) = 0$ $x(x+2) = 0$

Either factor can be 0.

$x + 2 = 0 or x = 0$ $x +2 = 0" or " x=0$

$x = - 2 or x = 0$ $x = -2 or x=0$

How do you solve x2+2x=0x^2 + 2x = 0?
