Solution

The correct option is D $x = 0, - 2$
The given equation is $x^{2} + 2 x = 0$

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

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

$∴ x = 0$ or $x = - 2$

Two distinct polynomial f(x) and g(x) are defined as follows:

$f (x) = x^{2} + a x + 2; g (x) = x^{2} + 2 x + a$

If the equation f (x) = 0 and g(x) = 0 have a common root, then the sum of the roots of the equation f (x) + g(x) = 0 is
