# Solve

Hint:

### Rearrange the equation and then solve.

## The correct answer is: x = - 2

### Complete step by step solution:

Here we have the equation

On subtracting 1 from both the sides, we get

To make the power of the equation as 1, we have to raise the equation by

On rearranging, we get

Now, this is a quadratic equation with a = 1, b = 4, c = 4

Roots can be found with,

On solving, we get x = - 2

On rearranging, we get
