Answer:
see explanation
Step-by-step explanation:
The steps required in the solution are
Add 1 to both sides
Take the square root of both sides
Subtract 3 from both sides
-----------------------------------------
Given
(x + 3)² - 1 = 35 ( add 1 to both sides )
(x + 3)² = 36 ( take the square root of both sides )
x + 3 = ± [tex]\sqrt{36}[/tex] = ± 6 ( subtract 3 from both sides )
x = - 3 ± 6, thus
x = - 3 - 6 = - 9 or x = - 3 + 6 = 3
