Question

Solve (x - 5)² = 3.

A. x-5± √√3
B. x = 8 and x = -2
C. x=-5± √√3
D. x=3 ± √√5

Answer 1

Answer: A

Explanation:

(x - 5)^2 = 3

take square root of both sides

(x - 5) = +-sqrt 3

you can remove the parentheses

x - 5 = +-sqrt 3

isolate the x variable

x = +-sqrt 3 + 5

Answer 2

A

Explanation:

(x-5)^2 = 3

Take the square root of both sides

You are now left with: x-5 = sqrt(3)

Add 5 to both sides

x= 5 + or - sqrt(3)
