Question

Which of the following equations has solutions of 3 ± square root of 5 ?
(x - 5)2 = 3
(x - 3)2 = 5
(x + 3)2 = 5
(x + 5)2 = 3

Answer 1

For (x - 5)^2 = 3
x-5 = ± sqrt3
x = 5 ± sqrt 3

For (x - 3)^2 = 5
x -3 = ± sqrt 5
x = 3 ± sqrt5

For (x + 3)^2 = 5
(x + 3) = ± sqrt5
x = -3 ± sqrt5

For (x + 5)^2 = 3
x + 5 = ± sqrt3
x = -5 ± sqrt 3

So, what's the answer?

Answer 2

second one

Answer 3
