Question

What are the answers for question 1 and 2??

Answer 1

1) Answer: 3) ~~x = -3 \pm \sqrt{7}

2) Answer: 3) 2 and -6

Explanation:

Answer 2

1) Answer: 3)
`~~x = -3 \pm √(7)`

2) Answer: 3) 2 and -6

Explanation:

1)

`(x + 3)^2 = 7`

`x + 3 = \pm √(7)`

`x = -3 \pm √(7)`

Answer:
`3)~~x = -3 \pm √(7)`

2)

`2(x + 2)^2 - 4 = 28`

`2(x + 2)^2 = 32`

`(x + 2)^2 = 16`

`x + 2 = \pm √(16)`

`x + 2 = \pm 4`

`x + 2 = 4` or
`x + 2 = -4`

`x = 2` or
`x = -6`

Answer: x = 2 or x = -6
