Answer:

Step-by-step explanation:
Comparing it with quadratic equation
, we get:
a = 1 . b = 4 and c = 5
So,
Discriminant = 
D = (4)²-4(1)(5)
D = 16 - 20
D = -4
Hence,
Discriminant = -4

Answer:
103
Step-by-step explanation:
The sum of angles in a quadrilateral is 360°, so the measure of x° is ...
x° = 360° -127° -90° -40° = 103°
x = 103
Solve by completing the square:
x² + 16x + 64 = 13 + 64
(x + 8)² = 77
x + 8 = +/- √77
x = - 8 +/- √77
OR
x = - 8 - √77, - 8 + √77
