##### Step 1) We multiply the numerators together and the denominators together: ##### Step 2) We simplify the result. To do so, we factor the numerator and the denominator: ##### where we have used the following expressions: ##### now, we simplify: ##### To find the non-permissible values, we have to set the denominator of the original result of multiplication equal to zero and solve for x. ,

##### since we have the product of two terms, we have to set each term equal to zero and solve for zero ##### Step 1) We multiply numerators together and denominators together .

##### Step 2) We simplify the result .

##### We set the denominator of the original fraction equal to zero and solve for x to find the non-permissible values
