Answer 1

Tried anything yet?

Answer 2

I don't think completing the square makes much sense here honestly lol.

Answer 3

Well you can use it, x^2 = 49, x = 7, x = -7 not very helpful lol.

Answer 4

You can simply add 49 to both sides and then take the square root. Problem solved, no reason to over complicate this I think lol.

Answer 5

(x^2-a^2) = (x+a)(x-a)

Answer 6

Complete the square to solve for x.

x2−49=0
