Answer:

Step 3 they took the square root incorrectly

Step-by-step explanation:

5 ( x-2)^2 +6 = 86

Subtract 6 from each side

5 ( x-2)^2 +6 -6= 86-6

5 ( x-2)^2 = 80

Divide each side by 5

5 ( x-2)^2 /5 = 80/5

(x-2)^2 = 16

Take the square root of each side

sqrt((x-2)^2) = ±sqrt(16)

x-2 = ±4
