Step-by-step explanation:
Step-by-step explanation:
Angle ACB = Angle ZXY (given)
AB = XY (given)
CB = ZY (given)
Since they both display the SSA postulate, it does not guarantee that the triangles are congruent.

Answer:
I think you mean the equation is
![2 {x}^{2} - 2x - 1 = 0](https://tex.z-dn.net/?f=2%20%7Bx%7D%5E%7B2%7D%20%20-%202x%20-%201%20%3D%200)
And you must find
![delta = {b}^{2} - 4ac = 4 + 8 = 12](https://tex.z-dn.net/?f=delta%20%3D%20%20%7Bb%7D%5E%7B2%7D%20%20-%204ac%20%3D%204%20%20%2B%208%20%3D%2012)
