0 or the third option down

Explanation:

square root of 36-4(1)(9)

square root of 36-36

square root of 0

0

Answer 2

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:

`√( 36- 36)`

This simplifies to

`√( 0) = 0`

The correct answer is the 3rd option.
