Answer:

A. and C.

Step-by-step explanation:

1. Plug in the values of a, b, and c into the quadratic formula:

[tex]x= \frac{-(-5)+-\sqrt{(-5)^{2}-4(1)(3) } }{2(1)}[/tex]

2. Solve the sqaure root:

[tex]x= \frac{-(-5)+-\sqrt{25-12} }{2(1)} \\\\x =\frac{-(-5)+-\sqrt{13} }{2(1)}[/tex]

3. Simplify the rest:

[tex]x=\frac{5+-\sqrt{13} }{2}[/tex]

4. Separate the solutions:

[tex]x= \frac{5+\sqrt{13} }{2} , x= \frac{5-\sqrt{13} }{2}[/tex]

A and C represent these solutions, therefore they are the anwsers.

hope this helps!
