xeze [42]

Answer:

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

2) Answer: 3) 2 and -6

Step-by-step explanation:

1)

$(x + 3)^2 = 7$

$x + 3 = \pm \sqrt{7}$

$x = -3 \pm \sqrt{7}$

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

2)

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

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

$(x + 2)^2 = 16$

$x + 2 = \pm \sqrt{16}$

$x + 2 = \pm 4$

$x + 2 = 4$ or $x + 2 = -4$

$x = 2$ or $x = -6$

Answer: x = 2 or x = -6
