Discriminant = b^2 - 4ac
a = 4
b = 16
c = 16
16^2 - 4(4 x 16)
256 - (4x64)
256 - 256 = 0
Therefore it only has one root
Two: the horizontal axis and the vertical axis.

Answer: 26/21 or 1 and 5/21
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by the reciprocal, so you can rewrite this problem as (4/6) x (13/7)
Next, multiply the numerators (4 and 13) and the denominators (6 and 7)
You will get 52/42, which can be simplified to 26/21 (you can also write this as 1 and 5/21)
Hope this helps
