Answer:
• add 1 to both sides
• take the square root of both sides
• subtract 3 from both sides

Explanation:
The order I gave shows how to solve the problem.

Here are steps...
(x + 3)^2 - 1 = 35
(x + 3)^2 - 1 + 1 = 35 + 1
(x + 3)^2 = 36
x + 3 +- = (square root symbol)36
x + 3 = 6
x + 3 = -6
x + 3 - 3 = 6 - 3
x + 3 - 3 = -6 - 3
x = 3
x = -9
