Mathematics
1 answer:
Brut [27]2 years ago
3 0

Answer:

Step-by-step explanation:

Let's go:

(x - 3)^2 - 10 = 15 \\\ (x - 3)^2 = 15 + 10 \\\ (x - 3)^2 = 25 \\\ x - 3 = \sqrt{25} \\\ x - 3 = \pm 5

Solution #1:

x - 3 = 5

x = 5 + 3

x = 8

Solution #2:

x - 3 = - 5

x = - 5 + 3

x = - 2

I hope I helped you.
