Answer 1

a=2
b=-5
c=2

y = [--5 +-sqroot(25 -4*2*2)] / 4

y = [5 +sqroot(9)]/4

y1 = 2

y2 = [--5 -sqroot(25 -4*2*2)] / 4

y2 = (5 -3) / 4

y2 = .5

Answer 2

Do you see why c=2 and NOT c=-2?

Answer 3

kinda its because it has to be a positive...

Answer 4

so it would be A

Answer 5

No.
In order for the quadratic equation to work, the equation must always be set up
ay^2 +by +c = 0

and the answer is c

Answer 6

c.

Answer 7

ohh ok!!
