Answer:
The roots are


Step-by-step explanation:
we have

so
Group terms that contain the same variable, and move the constant to the opposite side of the equation


Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side



Rewrite as perfect squares

square root both sides



By definition we have to:
In mathematics, an irrational number is a number that can not be expressed as a fraction m / n, where m and n are integers and n is different from zero.
For example, the number π is an irrational number.

We must find an irrational number between 5 and 7.
We then have the following number:

Answer:
An irrational number between 5 and 7 is:
