Solve the following quadratic function by utilizing the square root method. y = x2 - 64

Step-by-step explanation:

All you need to do is isolate the x.

First, add 64 to both sides:

Then, take the square root of both sides:

Actually, that is:

Here's the reason for that. An example would be:

Here, you'd take the square root of both sides to solve for x.

Right? But X could also be a -2, because a negative times a negative is a positive.

Therefore, or

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
