Question

Solve the quadtdd atic function (x + 1)2 = 16​

Answer 1

x = 15 or x = -17

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
