Answer:

2 → 15; -1

Step-by-step explanation:

1. -

[tex](x-7)^{2} - 27 = 37\\(x-7^{2} = 37 + 27\\(x-7)^{2} = 64\\x-7 = \sqrt{64} \\x - 7= \sqrt{8^{2}}\\ x = 8 + 7\\x = 15[/tex]

2. -

[tex]x-7)^{2} - 27 = 37\\(x-7^{2} = 37 + 27\\(x-7)^{2} = 64\\x-7 = -\sqrt{64} \\x - 7= -\sqrt{8^{2}}\\ x = -8 + 7\\x = -1[/tex]
