X={6,-10} that is the answer
Answer:
96 sq. cm.
Step-by-step explanation:
A "kite" has 2 diagonals, which are the "width" and "height" of the kite.
Using diagonals, the area of a kite is given by 
Where
A is the area
p,q are the width and height, respectively
From the problem given, p is 12 and q is 16, so the area is:

Thus, the area is 96 sq. cm
Quadratic Formula is (-b ±√(b²-4ac))/2a
With that being said:
y=2x²-5x-1 is in the correct form of ax²+bx+c
Now just plug in:
5±√(25-4(2 x-1))
5± √25+8
(5±√33)/2(2)
