discriminant $= 20$ $=20$

The discriminant can be calculated with the formula:

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

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

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

$:.$ , the discriminant is $20$ .
