Answer:
x = 15 or x = -17
Step-by-step explanation:
It is given that,
(x + 1)² = 16
To solve the quadratic equation
The give equation is
(x + 1)² = 16 ----(1)
From equation (1) we can see that it is a quadratic equation
So we can take square root fro both sides we get
√[(x + 1)²] =√16
x + 1 = ±16
x + 1 = 16 or x + 1 = -16
x = 16 - 1 = 15 or x = -16 - 1 = -17
Therefore x = 15 or x = -17
