Step-by-step explanation:
The quadratic formula is:

The discriminant of a quadratic is just the expression under the square root, or
. This can tell us the number of solutions a quadratic has.
If the discriminant is:
- Positive = 2 real solutions
- Equal to Zero = 1 real double/repeated solution
- Negative = 0 real solutions, but 2 imaginary solutions
Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.

Answer:
15.6855577203
Step-by-step explanation:
1. The square root of 5 is 2.2360679775 because you divide 5 by 2.
2. The you add 8+3=11.
3. Now you add 2.2360679775 and 11 which is 13.2360679775.
4. The square root of 6 is 2.44948974278
5. Now add 2.44948974278 and 13.2360679775 which is 15.6855577203
