Answer:
a
Step-by-step explanation:
Given
3(x + 3)² - 81 = 0 ( add 81 to both sides )
3(x + 3)² = 81 ( divide both sides by 3 )
(x + 3)² = 27 ( take the square root of both sides )
x + 3 = ±
= ± 3
( subtract 3 from both sides )
x = - 3 ± 3
x = - 3 - 3
or x = - 3 + 3
→ a
X=4 because you combine 2+4 and subtract -6 then divide
