1. 8%2Fx...value of x is not permissible in the following expressions is x=0

2. 5%2F%28x-9%29........value of x is not permissible in the following expressions is x=9%7D%7D%0D%0A%0D%0A3.+%7B%7B%7B%28x%5E2-x-12%29%2F%28x%5E2-5x%29...->..x%5E2-5x cannot be zero...
x%5E2-5x=0%29
x%28x-5%29=0%29
x=0
x-5=0%29..->..x=5
....values of x are not permissible in the following expressions are x=0 and x=5

4. %28x-6%29%2Fx%28x%2B6%29...}...->..%28x%28x%2B6%29%29 cannot be zero...

x%28x%2B6%29%29
x=0
x%2B6=0%29..->..x=-6
...values of x are not permissible in the following expressions are x=0 and x=-6

5. %28x%5E2-3%29%2F%28%28x%2B2%29x%29=8.......values+of+%7B%7B%7Bx are not permissible inthe following expressions are x=0 and x=-2
