Solve by taking the square root of both sides.
horrorfan [7]

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 = ± \sqrt{27} = ± 3\sqrt{3} ( subtract 3 from both sides )

x = - 3 ± 3\sqrt{3}

x = - 3 - 3\sqrt{3} or x = - 3 + 3\sqrt{3} → a
