$\"\"$

\

The functions are $\"\"$ and $\"\"$ .

\

Find $\"\"$ .

\

$\"\"$ (Division of functions formula)

\

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

\

$\"\"$ (Rewrite the numerator)

\

$\"\"$ (Take common factors)

\

$\"\"$ (Factorize the numerator)

\

$\"\"$ (Cancel the common terms)

\

Since $\"\"$ makes the denominator $\"\"$ , hence $\"\"$ is excluded from the domain of $\"\"$ .

\

$\"\"$

\

Find the domain of the function.

\

The function is $\"\"$ .

\

The denominator of the function is never zero..

\

$\"\"$ (Factors)

\

$\"\"$ (Simply)

\

Therefore, the domain of the function is $\"\"$ .

\

$\"\"$

\

The resulting function is $\"\"$ and domain is $\"\"$ .
