Answer:

Standard Form:

$1. \: {x}^{2} - 8x + 16 = 0$

$2. \: {3x}^{2} + 2x + 5 = 0$

$3. \: {3x}^{2} - 7x - 12 = 0$

Discriminant:

Step-by-step explanation:

Solution when finding the Discriminant:

$1. \: { - 8}^{2} - 4(1)(16)$

$64 - 64$

$= 0$

$2. \: {2}^{2} - 4(3)(5)$

$4 - 60$

$= - 56$

$3. \: { - 7}^{2} - 4(3)( - 12)$

$49 + 144$

$= 193$
