Thus ;

=======================================

Point :

Remember from now on ,

In quadratic functions ;

if :

The function has two roots

if :

The function has just one root

if :

The function doesn't have any root.

=======================================

Thus , ( x² + 6x + 13 ) doesn't have any root.

So ; ( x = - 2 ) & ( x = - 4 ) are the only roots.
