Step-by-step explanation:
questions 8, obviously the mid part of the parabola is 3, that is the axis of symmetry.
question 9, only one solution because you only have one parabola.
Step-by-step explanation:
The given quadratic equation is :

The formula to solve a quadratic equation is :

Put a = 13, b = 10 and c = 1
So,

Hence, this is the required solution.

The constant is the term that does not have a variable, hence why it is a constant. In this case:
-4 is the constant.
