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.
−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.
