Mathematics

Step-by-step explanation:

Step 1: Add 5 to both sides

2(x + 2)^2 - 5 = 93

2(x + 2)^2 - 5 + 5 = 93 + 5

2(x + 2)^2 = 98

Step 2: Divide both sides by 2

2(x + 2)^2 / 2 = 98 / 2

(x + 2)^2 = 49

Step 3: Take the square root of both sides

$\sqrt{(x + 2)^2} = \sqrt{49}$

x + 2 = 7

Step 4: Subtract 2 from both sides

x + 2 - 2= 7 - 2

x = 5
