%28x-8%29%5E2+=+25. We can take the square root of both sides, but we have to note that we can take the negative of the square root. We get x-8+=+5 and x-8+=+-5, so x = 13 or 3.

Take the square root of both sides:



So:



or



Since the roots are rational, the numerical answers are exact and there are no approximate solutions, per se.
