We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:
[tex]x= \frac{-b+- \sqrt{ b^{2}-4ac } }{2a} [/tex]
b = coefficient of x term = 5
a = coefficient of squared term = 1
c = constant term = 7
Using the values, we get:
[tex]x= \frac{-5+- \sqrt{25-4(1)(7)} }{2(1)} \\ \\ x= \frac{-5+- \sqrt{-3} }{2} [/tex]
So, the correct answer to this question are option E and F
