So for this problem, we can use the formular:
(A + B)² = A² + 2AB + B²
Our orginal expression is: (x + 4)². In this expression, A can be written as x, B represents for 4, that leads to our answer:
(x + 4)² = x² + 2 . 4x + 4² = x² + 8x + 16
The correct answer will be D
Answer: the correct option is (D)
