Answer:

x = 5 ± \sqrt{17}

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 = ± \sqrt{17} ( add 5 to both sides )

x = 5 ± \sqrt{17}

Thus

x = 5 - \sqrt{17}

x = 5 + \sqrt{17}

3. Because the numbers are positive when divided.

4. The inequality sign is reversed because the 2nd to last step is divided by by a negative number. (This is also the same for multiplication)
