Question

How do you solve `(X-8)^2=144`?

Answer 1

`x=-4,20`

Explanation:

We can take the `+-` square root of both sides to get:

`x-8=+-12`

We can now split up this equation into the following:

`x-8=12` and `x-8=-12`

Adding `8` to both sides of both equations simultaneously, we get:

`x=20` and `x=-4`
