$x = - 4, 20$ $x=-4,20$

We can take the $\pm$ $+-$ square root of both sides to get:

$x - 8 = \pm 12$ $x-8=+-12$

We can now split up this equation into the following:

$x - 8 = 12$ $x-8=12$ and $x - 8 = - 12$ $x-8=-12$

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

$x = 20$ $x=20$ and $x = - 4$ $x=-4$

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