Which of the following are solutions to the equation below?

Check all that apply

x2 - 8x + 16 = 5

x = 4 ±sqrt (5)

Step-by-step explanation:

x2 - 8x + 16 = 5

Complete the square

(x-4) ^2 = 5

Take the square root of each side

sqrt ((x-4) ^2) = ±sqrt (5)

x-4 = ±sqrt (5)

Add 4 to each side

x-4+4 = 4 ±sqrt (5)

x = 4 ±sqrt (5)
