### Assignment 8

Solve:

### Solution

The domain of the function in the left-hand side is:

or

We rewrite the equation:

The solution of this equation is:

thus:

or

Both solutions lie in the domain and are valid solutions.

Note. Compare this equation with the following assignment.

Solve:

In this case the domain of the function in the left-hand side is:

and

thus:

We proceed in the same way as before, with as result the solutions:

or

However, now the first solution does not satisfy the equation because it lies outside the domain.
