Question

Complete the square: (x - 4)^2 = 49 (I'd like help, not answers) =)

Answer 1

This is just a practice question, but I don't know how to do it and can't find anything in the lesson

Answer 2

x = 12
x = 11
x = 4
x = -3

Those are the choices

Answer 3

49 = (what number)^2?

Answer 4

7

Answer 5

good,
so, (x-4)^2 = 7^2
see the outlet?

Answer 6

Not really (sorry, I'm not good at math)

Answer 7

take off the square both sides, what are left?

Answer 8

(x -4) ^2 = 7 ^2
take off the square both sides

Answer 9

(x-4) = 7
or (x-4)(x-4) = 49?

Answer 10

nope, take off
x -4 = 7

Answer 11

now, +4 both sides

Answer 12

x = 7 - 4?

Answer 13

x - 4 = 7
x -4 +4 = 7 +4
x = 11

Answer 14

Okay. Sorry, wasn't paying attention to the sign. Makes sense. Thanks!
