Answer:

x = 5 ± [tex]\sqrt{17}[/tex]

Step-by-step explanation:

Given

x² - 10x + 25 = 17 ← left side is a perfect square, thus

(x - 5)² = 17 ( take the square root of both sides )

x - 5 = ± [tex]\sqrt{17}[/tex] ( add 5 to both sides )

x = 5 ± [tex]\sqrt{17}[/tex]

Thus

x = 5 - [tex]\sqrt{17}[/tex]

x = 5 + [tex]\sqrt{17}[/tex]
