Answer 2

ANSWER

0

EXPLANATION

The given expression is:

$\sqrt{ {b}^{2} - 4ac}$

We want to find the value of this expression when, a=1, b=-6 and c=9.

We substitute the given values into the expression to obtain:

$\sqrt{ { (- 6)}^{2} - 4(1)(9)}$

We evaluate to obtain:

$\sqrt{ 36- 36}$

This simplifies to

$\sqrt{ 0} = 0$

The correct answer is the 3rd option.
