Answer:

Step-by-step explanation:

Given

x² - 18x + --- = 4 + ----

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 9)x + 81 = 4 + 81

(x - 9)² = 85 ( take the square root of both sides )

x - 9 = ± $\sqrt{85}$ ( add 9 to both sides )

x = 9 ± $\sqrt{85}$ ← exact solutions

The answer would be ~30~ because 2*2^3 = 2^4= 16 then 3*6=18 then 16+18-4=30

Hope this helps
