Formula
x = ( - b <img src="https://tex.z-dn.net/?f=%2B-%20%5Csqrt%20%28b%20%5E%7B2%7D%20%20-%204ac%29" />) / 2a
solucion
(x - 5) ^ 2 = 144
x ^ 2 - 10x + 25 = 144
x ^ 2 - 10x + 25 - 144 = 0
x ^ 2 - 10x - 119 = 0
a = 1 b = - 10 c = - 119
x = ( - b <img src="https://tex.z-dn.net/?f=%2B-%20%5Csqrt%20%28b%20%5E%7B2%7D%20%20-%204ac%29" />) / 2a

x = (10 + - 24) / 2
<img src="https://tex.z-dn.net/?f=%20x_%7B1%7D%20" /> = (10 + 24) / 2 = 34 / 2 = 17
<img src="https://tex.z-dn.net/?f=%20x_%7B2%7D%20" /> = (10 - 24) / 2 = - 14 / 2 = - 7.
