discriminant$= 20$

#### Explanation:

The discriminant can be calculated with the formula:

$D = {b}^{2} - 4 a c$

Substitute your known values into the equation to find the discriminant:

$D = {b}^{2} - 4 a c$
$D = {\left(6\right)}^{2} - 4 \left(4\right) \left(1\right)$
$D = 36 - 16$
$D = 20$

$\therefore$, the discriminant is $20$.
