Question

What is the intermediate step in the form (x + a)2 = b as a result of completing the

square for the following equation?
x2 + 34 = 10x

Answer 1

(x-5)^2=

(x−5)

2

Answer 2

So the intermediate step in question is (x - 10)² = 66

Explanation:

Let's find out:

x² + 34 = 10x

x² - 10x = -34

x² - 20x + 100 = 66

(x - 10)² = 66

x - 10 = ± √66

x = 10 ± √66

x ≈ 18.12, 1.88
