It is not specified what the question is asking for, so it is impossible to determine which one is the answer.
Solve the following quadratic equation using square roots: −9 (x−3)2−4=−4 .(1 point)
To solve the quadratic equation −9(x−3)²−4=−4, we can start by isolating the squared term:

−9(x−3)² = 0

Next, we can simplify by dividing both sides of the equation by -9:

(x−3)² = 0

Now, take the square root of both sides to eliminate the squared term:

√(x−3)² = √0

Simplifying further, we have:

x−3 = 0

Add 3 to both sides to solve for x:

x = 3

Therefore, the solution to the quadratic equation is x = 3.
